As long as American Govt is standing with Israel they are and should feel invincible, America will fight and let its own people die for Israel, just take a look at this very thread, we have Americans here literally justifying killing civilians, collective punishment, war crimes, and have no problem with USA literally threatening UN/ICC and ICJ to protect Israel's doing in Gaza. Israel's existence is now by in large tied to existence of USA as super power and "they" will make sure that no other Power such as China, Russia or India become powerful enough to challenge that order, The EU will tag along because they know the dethroning of USA from Super power title means the EU's superiority will have to settle down as well.
Palestinians maybe the under physical oppression from Israeli's but its the American people who are now complete slaves of the lobby, they don't realize this or do anything about it because they care about abortion rights, LGBTQ rights and other national issues, but as long as they have leaders who support their political position, they (American's) don't care about Arabs or brown people in large, they will gladly re-elect Biden for that very reason, no issues with Biden's past statements about " If there was no Israel, we would create one " or democrats pro-war policies as long as pride parades are happening, trans-kids get their puberty blockers or celebs tweeting #BLM, but what Americans don't understand that their choice of Govt and President effects the whole world not just their internal problems.
