In 2002 as the US was preparing to invade Iraq, she began negotiations for the creation of a Palestinian state and the roadmap to get there.
As a result, Pres Bush delivered his "vision speech" in which he committed the US to support the creation of a Palestinian state subject to certain provisos, namely, that they "build a practicing democracy, based on tolerance and liberty." and they stop "encouraging, not opposing, terrorism". These preconditions have not remotely been met.
The Roadmap was presented in 2003 just days after the invasion of Iraq began. It is obvious that the two were linked. Unfortunately it included reference to the Saudi Plan which required 100% withdrawal. When Israel balked at its inclusion Secretary Powell said the Roadmap is only a process and forced PM Sharon to accept it albeit with 14 reservations.
