It wasn’t intentional. Trump followed Putin just as Vance followed Trump. He is just too stupid to have seen how this would play out.

Getting attacked by a foreign leader is such an effective way to rally your people behind you, that governments often fabricate external threats as a way to unify their nation. Putin knew the ways this could play out. The only more desirable result for Putin would’ve been Zelenskyy reluctantly accepting the agreement, but globally discrediting the US was a guarantee.

Putin was a KGB intelligence officer for 16 years before going to work for Yeltsin. The man outsmarts intelligence experts for fun. Trump’s ignorance and ego make him the perfect patsy, and the greedy Republicans in office have fully manifested into spineless yes men that are guaranteed to stay out of his way.
