The accusation that anyone who understands the difficult situation Israel faces is a Jewish fundamentalist is absurd, we might as well say anyone that supports Palestine is a Muslim fundamentalist that wants Sharia law worldwide.
I'm not defending everything Israel has done but also I'm not dumb enough to think if the tables were reversed that Palestine would be smiling as Israel chucks rockets at it and saying 'we don't want to kill Israeli citizens so we're not going to fire back' we all know they'd have done what they often talk about and pushes the Jews into the sea.
I don't like the government of Israel but at least they care about their own citizens, Hamas are controlled by religious crazies like Iran who are more than happy to increase the suffering of their citizens just to create good propaganda - hence digging up water pipes to make rockets, stockpiling fuel underground while hospitals run dry, putting military facilities under schools and hospitals, blocking roads so civilians can't flee combat zones, and endless more examples.
