When the US ignores the region, Palestinian terror rises as Palestinians try to get attention and capitulation to their demands. So, America like it or not, perpetually tries to keep talks between Israel and the Palestinians going. The gap between Israel and the Palestinians is however too large so the endless loop of terror and talks continues. Sooner or later there will be compromise or defeat. The US is not going to impose defeat on their Israeli ally as the Palestinian supporters wish nor is it going to ignore its Arab interests.
