Israel invades the gaza strip.

Jews are not Christians.
Christians and Jews have been in a longer running war than Jews and Muslims, actually. Centuries upon centuries of anti-Semitisim in the form of pogroms, inquisition, blood-libel, "The Protocols of the Elders of Zion", the Dreyfus case (google "J'accuse") and finally that little altercation in Europe in the 1940's, have convinced both the Jews and the World that they need a place where they can rule and defend themselves.

Woops, my mistake, the 'muslims' pre-muhammad are also part of 'christianity' and the religious dispute sort of branched off and continued until now.

Muslims haven't even existed for thousands of years.
But yes, it's a long-running on-and-off dispute. However, there was no need to use the Palestinians as pawns in this game. The Arab countries could have taken them in, while still carrying on the Jihad against Israel. Having these poor people live in refugee camps for generations as an excuse for continued hostilities on Israel ("we must get these people's home back") and to make them desperate enough for suicide bombings and such, is absolutely unforgivable.

I think it should've been pretty clear that the arab countries do not want any more jews on-top of the population that they already had(again, religious threat). and what about the palestinians that were killed by the jews ? The UN shouldn't have meddled with the arabs in the first place.
