As for "conventional and unconventional weapons" being stationed in the West Bank, that seems quite unlikely. Even the Clinton parameters called for a demilitarised Palestine. Netanyahu continues to insist on that demand, and hell, even the Palestinian negotiating team at Taba essentially conceded that demand. Furthermore both Israel and the Palestinians now seem to be calling for an international (non-UN) force on the border, and both seem to be leaning towards an American-led force.
Anyway, I've no doubt there will be plenty of animosity for years to come. That's not the primary concern - the primary concern is keeping Israel a viable Jewish state, and removing the "Palestinian cause" as an Arab propaganda tool.
