You did not get what I said. As I stated explicitely, the point is not that there would be disagreement about attacking Gaza. The point is that the governing forces chose to escalate the situation into a major invasion to play tough before the elections, to catch the wind from Bibi Netanyahu's sail, who attacked them from the right. It can be this narrow-minded. And it happened before.
Let's remember Operation "The Grapes of Wrath", the 1996 bombing of South Lebanon most infamous for the shelling of the Qana shelter with 106 dead. That operation was ordered by the then interim government of Shimon Peres, who wanted to show himself strong before new elections. He still lost -- incidentally, to Netanyahu... *Lunatic*, n. One whose delusions are out of fashion.
It's the same mistake Democrats keep making in the US. You can't be more hawkish than republicans so why get into that game (yes Hillary, we do mean you) ? however democrats can be much more sensible and balanced, which is why Obama got elected.
So if the Israeli centre/liberal (laughable as that sounds) want to beat the far-right, they won't do it by starting a war. keep to the Fen Causeway
