Why didnt the international community sanction the Israelis Israel annexed the Palestinians land and carried out genocide against the Palestinians ?

A combination of interest, imperialism, hypocrisy, and of course Zionists in powerful positions in the west.
Listening to western diplomatic statements justifying sanctions on Russia, for example, you’d be forgiven for thinking international law was a holy set of commandments, faithfully adhered to as a matter of principal. However, you’ll soon snap out of it when you hear the same diplomats prevaricate and collectively shrug when asked to comment on Israeli annexation of territory, or the brutal war crimes in Yemen. Germany, which loves to act contrite and endlessly prattles on about how many lessons it learned from its genocidal past, couldn’t even pretend to care that it is supplying nuclear-capable submarines to an Apartheid state, by the admission of the largest human rights organizations in the world.
It is not a coincidence that Israel has always enjoyed the backing of the colonial powers of the world, especially the settler colonies which share similar origin stories, and it is not a coincidence that Israel is basically a client state of the world’s imperialist hegemon. Israel was useful to these powers at the time of its establishment, and it continues to function as an outpost for imperialism in the region today.
