I think the United States government has fallen into this trap which seems to be universal among empires across history; the only people in its institutions are those who unquestionably agree with the hegemon's goals and objectives; thus, there is no counterbalance as disagreement, of any kind, is seen as disloyalty and opposing views are attacked.
Compare JFK's cabinet with Biden's; JFK didn't seek out and retain yes men. For example, had it not been for someone challenging intelligence and experts and advising JFK to ignore recent letters clearly written by CCCP apparatchiks and to respond to the first, written in a simple and emotional style, indicating Khrushchev himself wrote it, the Cuban Missile Crisis would have been resolved in a deadlier manner.
Biden has a bunch, no, several venal diversity hires (Austin, his black wahmen SCOTUS pick, his DOJ BLM negress) and soycucks in State/Defense parroting neocon talking points. State is full of the very people that provoked and escalated this situation, any other President that wan't a nursing home dementia escapee would have fired them the moment this shit went hot and put in competent people who spoke Russian/Ukrainian, understood and lived Russian culture and most important, could relate to their Russian counterparts. Instead we have a hysterical overreaction more reminiscent of a underage teenage girl mad at her boyfriend for going out with another girl than of seasoned, professional diplomats and negotiators. I see unqualified diversity hires probably picked by a drunk Hillary Clinton proxy dragging us into this mess. Threatening China with sanctions tells me everything I want to know.
These are the people that scream to IT their computer is a POS and won't turn on and then you find out its not plugged in because their foot yanked the cord out during an intense Candy Crush level. They call your supervisor demanding to know why they can't install a chat program so they can IM during work. Then they use their phone to do it anyway. That's who's running the USA. All this can lead to turning not only Ukraine but your part of the world into Stalingrad, and with nukes.
