"Well Hamas has…" Yes, we know about Hamas’ often unscrupulous practices. But using that to justify Israel’s current actions is like saying because of the Bush administration’s mid-east havoc, Afghanistan has the right to come bulldoze the city of Los Angeles.
This is a false analogy. The invasion of Afghanistan was a retaliation against Al-Quaeda. Similarly, the attacks on Gaza are retaliation against Hamas attempting to invade and bomb Israel. The reason that many more have died in Palestine than Israel is not because the Israelis are more vicious or the Palestinians more virtuous, but because the Israelis are better armed and better organized, thus the damage is obviously going to be greater. Hamas cannot match Israel’s retaliation efforts, as demonstrated through continuous Palestinian aggression towards Israel being met with catastrophic retaliation efforts. I am for neither state as Hamas is comprised of thugs and fools and Israel’s military and government is sloppy and arrogant. I imagine if Israel wasn’t in the middle of several Muslim states allied with powerful nations like Russia they would probably be able to easily win the war.
