Haven’t seen any evidence that he negotiates with Putin or anyone else. Haven’t seen any evidence that he is capable of negotiation, intellectually, emotionally, on the basis of any respectable knowledge base of any topic of presidential level negotiation. Have seen evidence that he colludes with or acquiesces to Putin, even that he aspires to Putin like unchecked power. Trump corrodes and befouls pretty much every thing he touches, and now he has his hands all over the highest office in the land, an office that requires its holder to have the highest ethical standards. haven’t seen any evidence that he has any ethical standards at all, unless you call Mob rules “ethics”.
