Yes, Poland has consistently been the most pro-US country in continental Europe since before the Iraq invasion. I'd say they come right after the UK as far as unwavering support goes. Keep in mind that the historic perspective of Poland leads to certain ... concerns about being sandwiched between Germany and Russia, so they're eager to ally with the US. Trump has just recently decided to move a sizeable chunk of the US military stationed in Germany over there, too. They are also ridiculously lib on economic matters, the most leftwing party in their parliament are libertarians or something like that. It makes absolutely zero sense for the US to stage a colour revolution in Poland. Literally any other country in the EU would make more sense.
