There are nations that are urging Israel to practice restraint in protecting herself from her enemies. My question to you is: In whose interest is this call for restraint? Is it in Israel's benefit to show restraint at this time, or is it really in the interest of other nations with nothing to lose to call for restraint? Certainly no nation should have to (or would) sacrifice the security of her citizens for the interests of another nation.
And speaking of nations calling for restraint, I have some questions for Russia and China:
How much restraint was shown in Tienamin square?
How much restraint was shown in fighting Chechen rebels?
It is easy to call for restraint when you don't have much to lose. It's like being generous with someone else's money.
