You can’t separate Hamas the PLO and Palestinians. They are all Palestinians with just different factions. If what you were calling the Palestinians would take power than Hamas and the PLO would be nothing but a far right wing party without power. But since the more moderate group refuses to confront the more radical part of their people they get what they have now. That is why it is important to stand up to the groups that are radical on either ends of a spectrum. They should have a small voice where ideas can percolate and move into the more reasonable part of the spectrum. But when the radical portion of the group takes over the whole party this is exactly what you get.
