and EU isn't even a country, and all(?/most) EU countries have the budged strictly sitting with the senate, i.e. outside of the hand of any of the leaders discussing deals with Trump

the chance that anything like that will pass those Senats also isn't exactly high

and all of this is public knowledge, so either Trump is incredible badly consulted to a point you wonder if it's malicious or more likely he doesn't care, and only care about a meaningless legally void promise he can present now probably some way smaller immediate subset of the promised actions. And then a few years down it's the "evil other countries" which he knowingly pressured to give him hollow promises they legally can't give, instead of it's seemingly bad/incompetent deal making (if you assume the goal is to actually make working deals and not to rail up people to have excuses for increasingly more extreme actions).
