Not even close. Biden's team Israeli is pushing him to back an incredibly unpopular policy. They know it can't last, politico says that its weeks at most according to the insiders. I'd expect its not going to last that long.
Hezbollah is threatening to join now if it continues and world support for the US has tanked massively, especially amongst Muslim countries that were just recovering from the GWOT. This just clarifies that US foreign policy is always pretty much the same and that makes the world much less safe.
Israel has never been really threatened by Hamas, they have no army and even with a surprise they could only just barely get outside the prison walls for a day. They keep bragging about how great the Iron Dome is, so even the threat of homemade rockets isn't that serious.
What will be existential is only to the zionist movement. Its now tarred as a genocidal, racial supremacist movement with Jews now being arrested globally for protesting zionism.
The US is now actively taking part in the genocide. The pentagon confirms they are flying drones over Gaza and the US government debated and decided to send an extra $14 billion for bombs on Gaza. Those are moves of active participation.
The bigger question is whether Biden loses the youth vote and all the good will he was starting to accumulate and whether this dooms the dems. Same with Trudeau up here, is this going to damage his reelection hopes too?
