It isn't "the West", though.
The support for Israel comes from Western politicians, not the populace. This is a consequence of where Israeli influence operations have been focused (on politicians and associated networks) and it will come back to haunt all of them - it is creating an ever deeper gap between rulers and ruled.
The EU's position on Isreal
EU: We are a little concerned with what the Isreali govt is doing right now. Hey Germany, as the largest and most powerful member of the EU, we ask you to make a statement.
Germany: You want us???...?..to make a statement?????? Listen we aren't blind to what's goin on in the middle east but FFS COULD WE JUST STAY OUT THIS 1 ISSUE FOR IDK REASONS????!?!?!
EU: Welp that's it. Germany isn't on board, we can't do anything.
Germany: WE NEVER SAID THAT
EU: too late, the issue is closed, nothing will and can be done.
EU: let's remember to drag Germany in the middle of this the next time our voters ask us to do something about Isreal.
USA's position on Isreal
Dems: we are for a 2 state solution
Dems: CORRECTION most of us are for a 2 state solution some of us want gaza cleansed.
Biden: I am for a 2 state solution and I trust Bibi when he says a response is needed and it won't last long.
Biden's advisors: you know Bibi is a criminal, you shouldn't get in bed w/ him
Bibi: LOL you should of listened to your advisors. Ive crossed so many red lines you set that I broke the 1st down laser.
Trump (who is the entire republician party): If anyone asks I'll just say ITS A DISASTER. If Gaza is nuked meh, if Isreal is nuked by Iran meh. Hopefully they all kill each other as it has nothing to do with meeeeee.
