If the NATO treaty has found to have been abrogated by the EU (and I suspect there is lots of evidence for that, especially dating back to the Bosnian wars), then Trump’s idea of bilateral treaties/agreements with individual European countries ought to come into play. That can be a factor in uniting the European natives against the “migrants”, but not on the EU’s anti-US basis nor on the EU’s expansionist ambitions.
I would much rather President Trump negotiate treaties with individual nations rather than the EU as a whole.
As President Trump has said so many of our so-called “friends” have treated us so poorly over the years that now they believe it is their right to do so.
It is time to move on and find new more useful allies. There are many who would welcome us, Poland being one of them.
