Oh please, not again! Since when has Gaza belonged to anyone for it to be legally occupied. And what has that to do with the fact that Hamas lobbed bombs into Israel from Gaza? Is the argument that since Gaza was illegally occupied by Israel, that makes it all right for Hamas to bomb Israel when Israel left Gaza? Just to state that argument is to ridicule it. What is that novel by Huxley, "Brainless in Gaza"? No, "Sightless in Gaza", but it might as well be, "Brainless in Gaza".
After the 1948 Palestinian Civil War Israel was provided with a set of borders that were drawn up and did not include either Gaza or the West Bank. The Palestinians living in those areas administrated them as arab states and were forcibly disarmed. Gaza belongs to the Palestinians in the eyes of international agreements made at that time.
During the six day war Israel occupied Gaza and the Sinai in order to thwart the Egyptian army, both Israel and Jordan invaded the West Bank pretty much simultaneously, and Israel occupied the Golan Heights - probably in order to deny Syrian forces the high ground.
According to the internationally agreed rules of war to which Israel is a signatory, all these territories should have been given back. "To the victor the spoils" seemingly considered bad form after WW2.
In fact, the case could be made that Gaza and the West Bank deserved to be given back more than the Golan Heights or Sinai, seeing as the Palestinians didn't actually fight Israel during the six day war.
Instead, Israel kept a military presence in these areas and encouraged Isreali citizens to move there. This is almost certainly due to the law of return (any Jewish person being invited to immigrate) rendering Israel proper a rather cramped place to live.
Which conflicts with an article of international law called the right of return, which says you can't hand over a refugee's house or land to someone else if the refugees want to go back and live there.
In recent years Israel has restricted it's military presence to policing it's (illegal) settlements and "brown areas" (military assets such as firing ranges and so on).
This is sold as a "withdrawal from Gaza" - though it isn't really.
I don't think it's right for Hamas to attack Israel with rockets. I don't think it's right for Israel to treat the Palestinians the way they do. These are two peoples with a complex history of grievances - both of whom who have suffered and both of whom have caused suffering.
Huxley's novel is called "Eyeless in Gaza", by the way. What a book, a fiction at that, published before the creation of the modern state of Israel has to do with the current situation I'm not sure.
But thanks for the reading suggestion, in return I would point you to "Palestine" by Joe Sacco (for the human interest) or "Israel/Palestine : How to End the War of 1948" by Tanya Reinhart (though it is an unutterably depressing book).
