In Ukraine, yes. The US is fighting a proxy war against Russia. The last 30 years of NATO expansion and USA animosity against Russia are enough evidence in my opinion.
In Palestine, no. Israel and the USA are committing a Genocide against the Palestinians, or at least, is a USA backed Genocide.
Israel has been a key USA asset for destabilizing the region from, at leat, the times of Kissinger as secretary of state and to stop socialist panarab projects like then ones of Nasser or the Ba'aths parties.
