For the purposes of this conversation, I'm going to assume you mean the occupation started in 1967 - when Israel had to defend itself from 6 Arab armies. It was when Israel asked Jordan not to attack or else they would have to enter the West Bank. and East Jerusalem. You are spot on that the Palestinians rationalize it all through the prism of the victim. Both sides need to take some responsibility, including the Palestinians. Both are victims in ways, and both are the aggressors in ways. The fact you see it as a black and white conflict shows your lack of understanding or complete bias.
