The United States is revising its decision to exit Syria. Washington initially hoped to complete the withdrawal by April or, at the latest, the summer months. Yet the White House announced last week that 200 U.S. troops would remain on the ground for an unspecified amount of time to promote peace.
In fact, potential cooperation between China and Russia is mentioned as one of the significant threats for U.S. foreign policy. Of course this is the perspective of the U.S. and it is possible to read most of the decisions given by the U.S. administrations in the last few years in accordance with this changing threat assessment and perception.
