So liberia didn't, you know, disintegrate?
No. My rough-and-ready outcome for Liberia is a different Liberian Civil War, which begins in the late 1990s after the assassination of President Thomas Quiwonkpa. John McCain, who wins the 2000 presidential primaries and the election against Vice-President Mario Cuomo, sends the Marines in to protect American interests and restore order. Overwhelming force and support for the American intervention among both the international community and many Liberians means that they manage to bring a modicum of peace to the country.
By today, Liberia is doing better than OTL, but the government is an unruly coalition of parties kept in line with American money, the security forces are repressive if not outright monstrous, and the U.S. wages a drone war in West Africa from Liberian bases. There are a couple thousand U.S. troops still stationed on their soil, and they've been the target of terrorist attacks by Ansar al-Jihad, a Liberian jihadist group drawn primarily from the Mandingo and affiliated with other West African jihadist and Islamist groups.
