I don't buy that. Trump loves to fight. So why are the only people he chooses to suck up to are these dictatorships? Politically it's moronic. There has to be a reason for it. And the ONLY thing that makes sense, is that he's over a barrel somehow.
Intelligence Services know that when they buy some information from their enemy, they get more than whatever they paid for because they can always threaten exposure down the road. If Trump stops doing their bidding, the evidence of treason is leaked.
Not really. 45's a bully. He hits down, or at least in the direction that he perceives as down, because striking at a peer or superior is potentially going to get him hurt.
Most democratically elected leaders do what they can to maintain at least a statesman-like appearance and don't resort to childish name-calling and attempted strong-arm tactics as their first choice of how to deal with people. While 45 seems to look on it as a way to put his "opponent" off balance so he can "win" the exchange. He's the person who looks at the person not responding to the catcalls as weak, rather than as someone with the strength of character to ignore the petty stuff in order to get what needs doing done.
Contrasted with the people he sucks up to (MBS, Putin, etc) who take steps to emphasize their apparent strength all the time. Essentially, they put out the appearance that if you tangle with the bear, you're going to get mauled, and 45 believes it, because that's how he operates.
And it probably doesn't hurt that he is financially beholden to the Saudis and Russian oligarchs.
45's also incredibly shallow. His actions very clearly indicate that if something isn't "in your face" apparent, then it isn't true, because he cannot perceive what lies beneath. It's why he goes for the furnishings that would make Louis XIV go, "You should try to be less ostentatious." It's why he chose Mattis to be his SecDef, or keeps changing wives for younger and hotter models.
And he certainly doesn't get the idea of altruism - if its not to his benefit, then he doesn't care, or worse, sees it as a threat to be beaten back.
It would have taken effort to pick a worse person to be POTUS.
