We don't know if there's a coherent plan, or what the exit strategy might be, or even if we're still on the same side of the war we were on last October, but more U.S. troops are now expected to head to Syria.
The U.S. military has drawn up early plans that would deploy up to 1,000 more troops into northern Syria in the coming weeks, expanding the American presence in the country ahead of the offensive on the Islamic State’s de facto capital of Raqqa, according to U.S. defense officials familiar with the matter.
That's 1,000 in addition to the current 1,000, and comes as those troops are increasingly being asked to step in to prevent violence between our various semi-allied factions. The new troops would also act primarily as advisers, though that decision, too, is expected to soon be revisited.
As for the "plan" part, that's still up in the air.
The implementation of the proposed plan, however, relies on a number of variables that have yet to be determined, including how much to arm Kurdish and Arab troops on the ground, or what part regional actors, such as Turkey, might have in the Raqqa campaign.
Those would seem to be vital questions. It would be nice to get that pinned down before doubling our ground forces in the country. While the effort to take Raqqa is expected to be successful, the aftermath will likely look similar to the current situation in Manbij, where U.S. troops are attempting to keep a tenuous peace between warring allies, pro-Syrian forces, and Russian military forces backing Assad.
