As a simple stochastic strategy it would just make logical sense: throw money and praise at as many Western elites as possible, and hope some of them rise to positions of political power. For someone with an ego and intellect as vulnerable to praise and manipulation as Trump, coupled with his need for financial backing due to lackluster business performance, it would be a slam dunk. The book, American Kompromat is seeming all the more believable in light of his recent actions.
"This is going to be great television. I will say that.” - Donald Trump, after his meeting with Zelensky on February 28th.
It was clearly and obviously a preplanned ambush, a stunt for his base. Trump knows his base don't read, they don't understand the history of Ukraine or geopolitics - all they will pay attention to is emotional based reality TV. Hence why Zelensky was provoked by Vance. They just needed a reason to go for the jugular, and apparently Zelensky daring to challenge his majesty and speak up for basic facts was enough. Through all the sound and the fury (signifying nothing), Zelensky was only trying to warn America, nothing more.
