Last month, President Trump announced the immediate and complete withdrawal of U.S. forces from Syria. Then he backtracked, declaring that the U.S. withdrawal is contingent on benchmarks set by national security adviser John Bolton and Secretary of State Pompeo: destroying ISIS and security guarantees for the Kurds in Syria. Now, the current course is unclear.
Why it matters: Although U.S. forces cannot stay in Syria forever, withdrawing them too hastily could create a vacuum for ISIS to fill. While Turkey has pledged to fight ISIS, Erdogan's agenda is eradicating Kurds, whom he calls "terrorists." If Turkey attacks, many Kurds would be killed or displaced.
