The US Security Chiefs Aren't in Full Control

I think what the events showed us is that the security chiefs at this summit aren't necessarily in full control. Who are the actual Palestinian groups or factions carrying out this violence? Is there any overarching authority who can tell them, hey, put an end to this? The US is going to want to see Netanyahu stick to the pledge that was given at the October summit. They're not going to wants to see approval of new plans next four to six months as Israel committed to do.
