It's been up for debate since the end of World War 2 and it will continue to be up for debate for as long as it exists, we're debating it right now. I've read books on the topic, such as The Case for Israel (2003) by Alan Dershowitz; their arguments are unconvincing. Do you suggest that I have a right to my ancestral lands in Scotland? Or better yet the Annapolis valley in Nova Scotia? I am of Acadian descent and my people were forcibly deported from their lands only 255 years ago. Do I have the right to go there with my bulldozer and remove peoples homes? The Jews that were there before 1948 have every right to stay I am only referring to the vast majority that came from Europe that are phenotypically white Europeans, and their descendants. Then again perhaps they have the right of the conqueror as we do here in Canada and the United States. If you except the right of the conqueror then they have every right to exist and they have a right to exterminate the Palestinians much like the British did to the Natives here in Nova Scotia and other parts of North America, we even had a bounty on their scalpes. But they wont leave your 100% correct but just because they wont do something doesn't mean it wouldn't be a solution, and from where I'm standing it's the only peaceful solution. The other options all end in violence and death for millions, and if we live long enough I'm sure we'll get to witness it. Like I said it's a sad hopeless situation.
