The problem is the long term unconditional support for Israel from all the large nations. And the multitude of one-sided propaganda. Israel knows they can commit humanitarian crimes and steal land without repercussions because if anything happens they can cry to the US for help. We've already destabilized all their neighbors (Iran, Iraq, Syria, Lebanon, Palestine). It hurts knowing how much all these people have lost but they are the most fearless and will never back down to Israel.
