Trump won't be able to stop Swedish/Danish/Polish/Estonian/Finnish militaries from defending EU soil from these kinds of intrusions. Whether putin has or does not have a hold over Trump is no longer relevant I think, US politics is so far down the toilet I don't think anybody here realistically believes that things will get better on their own, we're all just hoping that the US as a nation survives. For all our sake I hope it does too but it looks pretty grim.
