I live in Kyiv. Air defense systems from US literally saving lives here. So I don't think your government doing only wrong things. And I don't think US continues war in Ukraine. Russia invaded my country in the spirit of 19th century imperial warfare. I don't see anything wrong with your country disagreeing with it. And I don't see where here the motivation to stay in power.
My feeling is that you want to destroy both the good and the bad that you have in your country. 
 

 You are right,up to now America still is the greatest country all over the world. I wish US could keep good and abandon bad.
