It doesn’t matter much which party is in power. US policy rarely changes because said policy is drafted by deep state policy makers and the intel community.
The UK deepstate and US deepstate are partners. The media in the UK reflect UK deepstate policy.
Here is how the UK media view the EU (top right):

"DON'T LET IT HAPPEN: EU boss Junker and his cronies want Corbyn to be Prime Minister"
Uk media fearmongers to voters for Tories, by calling the EU leaders - cronies. UK media: "Don't vote for Corbyn, that would be crazy, the sinister organization of the EU likes Corbyn. Nuff said.".
These are the same UK media that shills for the corrupt British Royals.
Qanon Trumpers are the Faux News Agenda. And preach UK partnership and vilify the EU. The same Faux News that promoted the cia endless wars. UK media also vilifies the enemy of the UK deepstate - the EU. As you said, both parties Dems and Republicans. Tories and Labour are in on it. Corbyn wasn't, so the UK deepstate media demonized Corbyn. Notice how same as anti-deepstate Corbyn was made the enemy, EU was linked with "sinister" Corbyn.
Tories were buddies with Putin Oligarchs. Putin backed Brexit. Trump backed Brexit. Yes, Europe is planned to be encircled. And yes the deepstate is behind this.
Explaining why Europe needs nukes in numbers comparable to Russia, so Russia is unable to do nuclear blackmail. More importantly Europe needs to run their arms industry production around the clock.
This Ukraine War is the Trump-Russian attack on the EU to finish off the EU. With planned high natural gas prices, planned high oil prices, planned economic collapse of the EU. This is the plan of Putin. Brexit UK and Russia Republicans oppose the EU.
