With Biden like that woman who gives hope Iran will again starting buying chocolate boxes hoping to carve a new relationship with the West. However down the road in 4 or maybe 8 years another US administration will come along and do another "Trump" on Iran. The suffering will be perpetuated. This is the story of US/West and Iran.
The other thing I note is Iranians blind themselves by seeing Europe as separate entity to USA. They should know while they may have differances but when it comes to Iran they are all on the same book, chapter if not the same page.
What you describe applies exclusively to the liberal political factions in Iran. Namely, the reformist parties (examples of reformist figures: former president Khatami, defeated presidential candidate Mousavi who lost to Ahmadinejad and subsequently instigated the 2009 fitna or "Green movement" colored revolution attempt) and the so-called moderate parties (examples of moderate politicians: ex-president Hashemi Rafsanjani, current president Rohani). The liberals hold sway over about half of Iran's economy, institutions, bureaucracy, media, etc.
Holding these liberal forces in check is the revolutionary core of the Islamic Republic, which broadly consists of the so-called principlist political parties, of Hezbollahi groups and social movements, of the Basij paramilitary mass-organization, of like-minded mosque and seminary networks etc. Ideologically, the revolutionary camp (referred to as "conservatives" in western media) has remained loyal to the original principles of the 1979 Revolution led by Imam Khomeini, in particular its anti-imperialist and anti-zionist dimension, whereas the liberal camp endeavours to reorient Iranian foreign policy towards gradual "normalization" with the west.
The revolutionaries have one major asset which the liberals lack and that is the alignment on their positions of the IRGC as a critical military and paramilitary corps. The Supreme Leader, for his part, is firmly situated in the revolutionary camp as well. Hence why you will see western and other mainstream media focus their attacks mostly on Supreme Leader Khamenei and on the IRGC, while being much more lenient towards reformists and moderates in their reporting.
Now independently of his political convictions, the Supreme Leader is no autocrat since the Islamic Republic is a genuinely pluralistic and democratic (albeit not a liberal-democratic) system. He sets general guidelines and broad policy frameworks to be followed by other institutions, but he must at the same time take into account the popular mandate of elected presidential administrations, as well as the different factions' effective political clout and capital. Unfortunately, his guidelines are not always followed by officials, particularly by liberal administrations like the current one (but even the Ahmadinejad administration developed some tendencies towards rivalry in its later years). Nonetheless the Leader must act as an arbiter between factions, even if his personal views are closer to one of these.
If it was entirely up to the revolutionaries and to the Supreme Leader, there would probably be no JCPOA in the first place and certainly no trust or hopes whatsoever placed on Biden. However, this is sadly not how things work.
The wish of every clear-sighted revolutionary and patriot right now is to see a strong sovereignist and anti-imperialist president, preferably a former military man, take over in the upcoming election. This would give the Leader a much freer hand to implement his policy guidelines. But western-based Persian language propaganda media are going to try everything in their power to prevent this from happening, by campaigning around the clock for the liberal candidate (which rumor has it will be current foreign minister Zarif).
Back to your observation, here is an article from Supreme Leader Khamenei's own website (a quality source, vividly recommended to those interested), highlighting what he thinks of EU regimes and their nonextant trustworthiness:
After the US withdrew from the nuclear deal known as JCPOA, the Leader of the Islamic Revolution gave a speech at Farhangian university and referred to the matter of continuing the agreement with three European countries, stating: "I do not trust these three countries and tell you not to trust...

Why aren't the three European countries reliable?
After the US withdrew from the nuclear deal known as JCPOA, the Leader of the Islamic Revolution gave a speech at Farhangian university and referred to the matter of continuing the agreement with three European countries, stating: "I do not trust these three countries and tell you not to trust them." Hence, the website of Khamenei.ir explores and issues some previous actions of these European countries against the Islamic Revolution of Iran and other countries, based on the statements of the Leader.
- Centuries of occupying and destroying other countries
Today, you can witness that the Americans and the Europeans have managed to conquer the entire world because of the knowledge they’ve acquired.
You know that the US, England, France, and many other European countries – even small countries in Europe – have managed to occupy other countries, some of them managing to keep ahold of those colonies for several centuries. They've [Europeans] exploited every resource that they had, and they destroyed them [regions the Europeans invaded]. They achieved absolute power over those nations, and they became dominant because of their knowledge.

- Colonizing of Algeria and Tunisia by France
As I said, our society of book readers, unfortunately, pays little attention to contemporary history. You should read contemporary history to see what happened to India, Burma, Africa and Latin America because of colonialism. You should read this history to see what happened in Algeria, Tunisia and other such countries at the hands of France – this seemingly orderly, neat, chic and polite country – and colonialism.

- A hundred years of conspiracy against the Muslim world
Hatching plots against the world of Islam and this region, in particular, is not a new development. Since many years ago -- since 100 years ago: World War I until today -- this region has been exposed to many pressures by arrogant powers. One day, it was England, one day it was America, and one day it was France. It is 100 years or more now that arrogant powers have been pursuing their goals here.

- Leading the front of Arrogance
The savage attack on Gaza, over the past week, which is truly shocking[...]--the shocking aspect is that leaders of the Front of Global Arrogance behave so shamelessly during this crisis. This front not only refuses to frown at the behaviour of the brutal Zionist regime, and they not only refuse to prevent it from carrying out its criminal activity, rather they support and encourage it. The USA, explicitly, supported the Zionists; England supported them; France supported them: these are the leaders of global arrogance. Muslims do not have any enemies who are as hated and brutal as these people.

- First sanctions, attacks, spying, propaganda invasions against the Islamic Revolution
From the Revolution onwards, you have seen what they have done. It is clear: the first round of sanctions, attacks, treacherous activities, espionage attempts, security infiltrations and the widespread propaganda attacks against the Islamic Republic were carried out by Westerners, by the Americans, and by the Europeans. And look what they did afterwards: before the imposed war, they helped leftist groups: those groups were leftists, but their supporter was rightist America!

- Trying to abolish the Revolution
The underlying issue had nothing to do with oil-rich regions; rather, it was about the essence of the Iranian government and the Revolution. They wanted to destroy the Revolution. The powerful US and Europe stood behind Saddam and helped him as much as they could. They helped him as much as possible! Second, third-rate countries in Europe were not important. The central powers of Europe--England, France, Germany, and Italy, countries which had power and capability in Europe--stood behind Saddam and supported him to the fullest.
And, at the beginning of the war, the troops of Saddam's regime were limited in number; and they had below average resources; but, with the passage of time – over a few years – these resources increased daily. However, war destroys resources. For example, at the beginning of the war we had tanks, but some of them were destroyed; we had some cannons, but many of them were ruined; we had ammunition, but all were used up; these things are naturally consumed during a war: war reduces resources. As the war went on, the resources of the Ba'athist regime increased. Who gave them these resources [weapons]? [It was]France, England, Germany, and the US.

- Equipping Saddam with advanced armaments and chemical weapons
The US used to help Saddam by giving him missiles, defensive weapons and even war plans. It used to help him with his satellites.
Others were helping him as well. France was helping as well. They used to give him missiles and planes. The same is true of Germany. Germany was giving him chemical weapons. You know that Saddam's army used to conduct chemical attacks on many occasions. We have so many casualties from those chemical weapons. Many of them have passed away! It was the Germans who were giving him the substances [to make weapons]. The Germans used to provide them with chemical substances so that they could produce chemical weapons.
Oct 18, 2017
In the middle of the war(8-years sacred defence), France gave its most advanced airplanes and helicopters to Iraq; and Germany provided Saddam's regime with chemical and toxic substances so that he could use them on the front lines.
[Ironically,] Those who are often attacking countries today, with accusations of chemical weapons use, officially and publicly gave chemicals to Saddam for making chemical bombs, and other chemical weapons, to use on the front lines.

- Accusing top authorities of Iran of Mykonos Affair
At one time, one of the European governments used to express friendship and a tendency to establish relations with Iran. The same government formed a court hearing after the Mykonos restaurant issue and levelled accusations against high-ranking officials of the country [Iran]. European governments cooperated with them, and all of them withdrew their ambassadors from Tehran. We have not forgotten those things. They tried to knock us across the face, but they received a stronger response.

- Following the US on sanctioning Iran and spreading propaganda against Iran
We have no problems with Europe either. It was the Europeans who clashed with us. I said to a European president, who had recently come to our country, that Europe should liberate itself from going along with the American's policies. The Europeans have followed along with American policies. He imposed sanctions on us, and they followed the USA. He made his propaganda against us, and they followed the US. Well, what should we do? In other events, it was the Europeans who began the enmity.

- Interfering with the defence power of the Islamic Republic
If European governments repeat the same thing that the US states; if they ask why Iran is present in the region – well, what is that to you? Why should Iran not be present? Or when they echo US criticism against our missiles, with a range of two, three thousand kilometres, this does not make sense. What is it to you? Why do you yourselves have missiles? Why do you, yourselves, have nuclear missiles? Why do you have atomic weapons? If they want to interfere in the defensive power of the Islamic Republic and speak against it, this cannot be done. We will not accept this from the Europeans, in any way! They should not sing along to the tune of the US when it sings songs of aggression and foolishness.

- French playing the role of the bad cop during JCPOA negotiations
What manner of hostility has the Islamic Republic ever shown towards France? Because Imam (r.a.) resided in France, for a while, that country was even praised by revolutionary forces, but you see how they treat Iranians today. You’ve witnessed that, on the nuclear issue, the French played the role of a bad cop. Of course, it was the Americans who set up this situation, but the French took on the worst position regarding the nuclear matter. What have we ever done to the French? Have we shown any hostility towards them?

- Obstinacy and malignancy during JCPOA negotiations
Sometimes one hears that I have expressed my dissatisfaction with this issue: some friends call it "the global community.” It is they that refer to themselves as the global community. We are not confronted by the global community. We are only confronted by the USA and three other European governments; that is all. It is, only, the USA and three European countries that show obstinacy, break their promises, and behave viciously towards the people of Iran on this matter.

Here is another example:
Khamenei says Iran should give up hope of European help against U.S. sanctions
Europe News
Reuters Staff
DUBAI (Reuters) - Iranian Supreme leader Ayatollah Ali Khamenei said on Thursday European countries were unlikely to help Iran against U.S. sanctions, and Tehran “should give up all hope” in that regard, according to his official website.
Britain, France and Germany, parties to a 2015 nuclear deal with Iran, have tried to set up a trade mechanism to barter humanitarian and food goods with Iran after the United States withdrew from the deal last year and re-imposed sanctions. But the mechanism is still not operational.
Iran has repeatedly said it will ramp up its nuclear activities unless the European countries do more to protect its economy from the impact of the U.S. sanctions.
“Despite their promises, the Europeans have practically adhered to America’s sanctions and have not taken any action and are unlikely to do anything for the Islamic Republic in the future. So one should give up all hope on Europeans,” Khamenei was quoted as saying.
“There should be no trust in countries that have held the banner of hostility to (Iran’s) Islamic system, led by the United States and some European countries, because they are openly hostile to the Iranian people,” Khamenei said.
“The road to interaction and negotiations is open to all countries other than America and the Zionist regime (Israel),” Khamenei told members of a powerful clerical body.

In other words, Supreme Leader Khamenei is very much aware of both the deceptive approach of the likes of Obama and Biden, and also of the "good cop" role assigned to EU regimes in the collective game played against Iran by the NATO and zionist axis (when Obama was in charge, the "bad cop" role was actually given to France).
Let us all hope and pray that the next Iranian president unlike the current Rohani administration will align more closely on the Leader's views.
