^..assuming that by "threats from the west" you really mean Amercian taxpayers footing most of the bill for defending Western Europe for 7 decades and counting yes you bet they are welcomed.
No, @LouiseCollins28, I mean hedge funds, vulture capitalists, pharmaceutical corporations, and the healthcare industry.
The Tories welcome these pirates with open arms, and welcomed the moral support of the various American think tanks funded by American billionaires which bolstered the case for Brexit, in particular the nexus of think tanks generated by George Mason University.
FYI, it was 100% in America's strategic interest to fund the Marshall Plan, to station troops in western Europe after WW2 (also in Japan), to fund NATO, to engage in the arms race, to court China, to depose governments considered unfriendly to the US, left, right and centre, and get involved in fighting against Communist backed enemies in Asia. It wasn't at all altruism on the part of the US.
Also -
The EU isn't a 'foreign power'.
It's a loose union of sovereign states.
The UK used to be a member and enjoyed all the powers and opportunities that all the other member states had.
