I hear what you say.
It's much more significant than just showing weakness to the dictator Russia, though (I'll check my door handles for Novichok from hereon), the display put on by Trump and his court jester today was utterly and completely disgusting to watch. It was playground bullying on an international scale - literally! More than that, it was the demeaning of a man who's country is literally in danger of not existing soon.
A man of any dignity does not conduct himself in such a manner.
The world is a far, far more dangerous place than it was a few hours ago.
