Israel stole the land from the Palestinians, killed and maimed thousands of civilians including children ever since it was created after WW2. Ever since it's creation Israel has been violating international laws left and right even it's creation was illegal under international law as a matter of fact. What did the so called west did about it? What does USA do about it? They send millions of dollars of aid every day to Israel, they fight wars for them and the media does rarely ever give a damn. Just compare how the media is reporting the Russian-Ukranian conflict and how it has been reporting Israel's occupation of Palestine. Israel has killed many times more Palestinian civilians then there will ever die in this Ukrainian conflict yet all you hear is "Putin is the new Hitler" thing. On top of that US media only ever cares about the little Poor Israelis how those evil Palestinian terrorists are attacking them yet there has probably been only a few Israeli civilian victims in the recent times, compare that to thousands of dead Palestinian civilians who had nothing to do with Hamas or any other resistance movement.
And now the rockets that are being fired to Israel. Those big bad Palestinian home made unguided rockets that can't do shit. Yeah what a thread to Israel, after all, how dare do the Palestinians dare to defend themselves from illegal invaders?
Here's a good video with sources about this conflict:
