Except, when it comes to US they probably do. Its not a secret, that US is acting in ukraine, from sending/heaving CIA agents to military advisers and probably weapons (but it's more from near nato countries than US directly)
And that's why I now believe that the 'crazy stalker ex' description is sorta accurate. USA \neq NATO \neq various European countries! It takes a big (and rather unhealthy) US fixation to see them behind everything any ally does.
The thing is, US would/is probably doing exactly that. Through nato neighbours to UK. What do you think, they will send their support directly from USA to UK? No, there is no need for that. They just need to pay for their nato alies to help arm UK. There is no need for some logistic expense, when you have nato next to them.
Ninjaedit: If you're throwing sovereignity out the window you're retroactively justifying the Iraq war, NATO's Balkan campaign, any possible Western involvement in the color revolutions... If you throw out sovereignity without offering anything to replace it you advocate a return to might makes right. And a waning middle power can only lose at that game when playing against the whole developed world.
Throwing ? No. I am just saying how things are, because of things you just posted here. Not saying how thing should be or how they should be replaced, just how the thing are. When it comes to big powers, there is no sovereignty, there is only interest.
EDIT: Also, let me say, the thing russia is doing is wrong, I am not saying because US/west did shit, it means russia can do it. No, russia is now as crap as west (or better said it always was like that).
