Advisory legal opinion from the International Court of Justice is summarised like this:

"In short, Israel is:
an Apartheid state
occupying Gaza
illegally annexing the WB
violating self-determination

This is illegal, so it must:
end the occupation
fully repair/compensate Palestinians, including through right of return & dismantelling settlements"
