security and cooperation necessary to combat" terrorism in the Maghreb. The letter referenced UN Security Council Resolution 1813 (2008), and encouraged President Obama to follow the policy set by President Clinton and followed by President Bush. The congressmen expressed concerns about Western Sahara's viability. They referenced a UN fact-finding mission to Western Sahara which confirmed the State Department's view that the Polisario proposal, which ultimately stands for independence, would lead to a non-viable state. In closing, the letter stated, "We remain convinced that the U.S. position, favoring autonomy for Western Sahara under Moroccan sovereignty is the only feasible solution. We urge you to both sustain this longstanding policy, and to make clear, in both words and actions, that the United States will work to ensure that the UN process continues to support this framework as the only realistic compromise that can bring this unfortunate and longstanding conflict to an end." Commenting on a 2004 free trade agreement with Morocco, US Trade Representative Robert Zoellick stated in a letter to Congressman Joe Pitts in response to his questioning, "the United States and many other countries do not recognize Moroccan sovereignty over Western Sahara and have consistently urged the parties to work with the United Nations to resolve the conflict by peaceful means. The Free Trade Agreement will not include Western Sahara." In April 2013, the United States proposed that MINURSO monitored human rights (as all the other UN mission since 1991) in Western Sahara, a move that Morocco strongly opposed, cancelling the annual African Lion military exercises with U.S. Army troops. Also in mid-April, United States Ambassador to Morocco Samuel L. Kaplan declared during a conference in Casablanca that the Moroccan autonomy plan "can't be the only basis in these negotiations", referring to the UN sponsored talks between the Polisario Front and Morocco. On 10 December 2020, President Donald Trump announced that the United States would officially recognize Morocco's claims over Western Sahara, as a result of Morocco agreeing to normalize relations with Israel.
