Very true. The anti Israel people on this board (though they deny that is their stance) never understand why rational governments support Israel. You see the confusion in their posts about this over & over again.
But as people with a more balanced view of the conflict understand, Israel could have been actually genocidal if they wanted to be - they could have bombed Gaza so extensively & indiscriminately they killed all of the Hamas operatives and supporters in there. Alongside many thousands of ordinary civilians of course but if they were truly genocidal in intent, would that bother them?
Israel has shown so much more restraint than their enemy would have shown them had the situation been reversed & Hamas been the stronger side.
That is why Hamas are designated a terrorist regime. Made up entirely of religious extremists like their paymasters in Iran, whereas the Israel government is not. Extremist regimes are the ones that get no support from functional governments around the world, they only support each other. Hamas & the Iranian government have this is common- they use fear & bullying tactics to oppress their own people. And they would be genuinely genocidal if they got the opportunity to destroy all Jews.
