Two objects may not occupy the same space at the same time.
If the Israelis want a secure homeland for themselves, then the only way is to remove the original inhabitants. You can't half ass occupy a piece of land, it's either all or nothing. A subjugated people can only be held down for so long, before they strike back. Seems like they need to read up on Joshua and see how a conquest is to be carried out.
And if the Palestinians want their land back, then they are going to have to do a hell of alot more to take it back.
