I roll my eyes at 99% of what he says/tweets, also. But, I think that you're wrong -- I think his 'adversaries' and 'counterparts' do end up bending towards what he think he wants much of the time. Doesn't matter if its EU, or Beijing....Fatty Fat or Saudi Princes....even Putin, perhaps.....if we're able to look back objectively in a few years, we might find that despite ignorant seeming words and actions, he ends up a lot closer to his objective than we ever imagined he might....
I was first to rail against the 'wall', but he may even get that...or at least enough pieces to declare a victory...still don't think Mexico is going to pay, though.....maybe charge those caravan-ers a toll to cross and use the tolls to pay for the wall....hmmm
