Well considering the fact that our region has been ruined by the same gang that now supporting Ukraine like invading Afghanistan, Iraq, Libya, Syria, Yemen and ... in one case in Iraq they provided Sadam with everything from CW to nuclear reactor and satellite footage.
The same happened in Yemen. So they can not take gesture of being innocent.
Second thing is, up until 2020 EU countries were selling weapons to Russia despite the fact that they said Russia invaded Crime:

"... According to “confidential-defense” documents obtained by Disclose and information from open sources, France has issued at least 76 export licenses for war material to Russia since 2015. Total amount of these contracts: 152 million euros. euros, as indicated in the latest report to Parliament on arms exports, without however specifying the type of equipment delivered.
According to the investigation, these exports mainly concern thermal cameras intended to equip more than 1,000 Russian tanks, as well as navigation systems and infrared detectors for fighter planes and combat helicopters of the Russian air force. Main beneficiaries of these markets: the companies Thales and Safran, of which the French State is the main shareholder..."
Not to mentioned were happy importing its 40% gas from it ... even despite they lessened the gas supply from Russia to just 20% they continued till September 2022.
On the other hand two decades of eastward NATO expansion up to Russia's borders, the European association agreement which provoked the Ukrainian crisis also included clauses to integrate Ukraine into the EU defense structure next to entirely unconstitutional takeover administration (including attacks on government buildings) when the Ukrainian president was replaced by a US-selected administration in 2014 (not to mentioned Orange revolution back in 2004) has pushed Russia to take desperate measures.
I mean the US and NATO are big part of the reason behind the war, like what they doing by "One China" idea ... selling weapons to Taiwan, sending diplomats there etc etc ... the US is poking China and probably one day in future would blame China for any conflict in that area,
Furthermore, Russia despite its performance is a military superpower with all type of BM, CM and a decent air force ... several hundred Iranians drones doesn't make that hell of change in the whole story.
PS:
The fact that EU-NATO-US consider killing civilians is ”fun” is probably an incentive to do something about it. It is said that revenge is a dish best served cold.
