Actually, those two cities had been left mostly undamaged by the war simply because they didn't have any major military value. We dropped the bomb there to show that we could kill anyone, anywhere, and you couldn't avoid it by going to non-military target areas.
This is terrorism on a TRUELY global scale. It's also arguably justified, as it probably saved many more lives on both sides by getting them to surrender.
Make no mistake--Israel is, and always has been, a fascist, apartheid state. They don't want to integrate because they would lose power, just like the whites did in South Africa when they gave up on their racist policies. If they used proportional response to terrorist threats, they would be a lot better off (and they would stop making more terrorists by their actions). Instead, they have to be "tough", and lob missiles into civilian areas and invade neighboring countries, etc.
Of course, America is guilty of the same thing, and on a larger scale, no less.
