[[If this is not a real treaty, can’t it just be withdrawn from by the next President?]]
There was soemthign that obama did that trump had a dickens of a time undoing that was not a treaty - obama got our nation into soemthing- can’t remember what now- and he did so without congress-
Could have been the Paris Climate Accord (I loved Trump for just pulling the plug on that) or the Intermediate-Range Nuclear Forces (INF) Treaty which was a real treaty (I think) that we had proof the Russians were violating. When they refused to provide concrete information proving they were in compliance, that met the requirement for a withdrawal and Trump did it.
That is why we supported him. He DID things that SHOULD have been done.
Also, he withdrew from the Universal Postal Union (Treaty of Bern 1874) which the Chinese Communists were using to great effect to smash us over the head.
Small Arms?
