You favor us staying in NATO? Why? When was the last time any one of those countries showed us an ounce of respect or lifted a finger to help us? Every one of them, especially Merkel and May are the first out of the box to condemn the US, no mater what we do.
How long do you think it will be until our military bases in Britain or Germany are attacked by Europe’s newer citizens?
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.
