This all comes from one fundamental fact: Refusal of most of the Arab nations and their "Palestinian" bully-boys to recognized Israel. If Israel had been accepted by 1967 none of the rest of this would be happening.

There is no reason on earth why they should have recognized Israel. However it is a lie to say that most of them did not do so. Many of them tried, but Israel would have none of it.

All of what has happened and is happening right now would have happened no matter what the "Arab" nations did or didn't do, because Israel has always created pretexts for committing acts of aggression against its neighbors for the purpose of taking more territory. And it will continue to do so, to the detriment of both the Palestinians as well as the Israelis, until either the people of Israel make them stop, or Israel succeeds in wiping out all of the people of the Middle East and possibly other parts of the world as well.
