People shrug off war so easily. They make it about winners and losers but they don't stop to think what it meant for the people who died.
In 1947 There was no state of Israel. There was Irgun and Haganah both terrorist organisations every bit as implacable and wicked as Hamas. There were bloody massacres and exterminations every bit as evil and wicked as Al Queda. There was land theft and murder and mayhem and terror to drive the inhabitants of Palestine away fleeing for their lives. So no, it isn't and it wasn't a matter of the good against the wicked it is the wicked against the defenceless on both sides and it still is.
[bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse] Christianity would expect that the Israelis would allow themselves to be exterminated in 1947. Bottom line, Israelis fought a war, beat the odds and won.
Neocons and militant Zionist might not be so shocked by immoral behavior as you might thing. Welcome to the real world, where war is a choice, and war has consequences.
In the meantime, the choice is between supporting freedom, or supporting Hamas. There is no third option.
So the morality of it is pretty clear.
