How could Trump be a Russian patsy and also be allowed to be President for 2 years? This is the part that does not add up. He seems obviously compromised but would US intelligence agencies and government officials really allow a President who was compromised to govern and to be trusted with national security secrets for this long?
A coup would be even more damaging. And it's not a binary thing. If Trump is not secretly FSB Colonel Trumpov, that doesn't mean he's acting in America's interests.
He could be compromised - blackmailed over recent or past dealings.
He could be afraid he's compromised, and is trying to curry favor or wheedle information.
He could be a stupid, greedy SOB who is selling out his country for promises of a hotel deal and bribes.
He could be a scared white-collar crook, making sure he does right by his ewually crooked "friends".
Or maybe he's just a useful and easily manipulated idiot.
In any case, "he can't be a Russian agent because if he was he wouldn't be president" is circular reasoning. He is President because the GOP values power more tha anything else. Russian connections aside, Trump is both grossly unfit and actively works against America's interests both at home and abroad. He might as well be a Russian agent, because he is slowly killing our institutions, like a radioactive poison. We ought to call him Trumpolonium.
