If we stayed in position, even with a nominal force, Turkey couldn’t attack the Kurds because they’d also be attacking a fellow NATO ally. Us.
Your idea isn't really realistic is it? Because if one guy wouldn't be enough then how many is enough? In reality Turkey is planning on attacking, and apparently already are. Our president was smart enough to move the US forces out of the area to avoid having them get caught up in the action.
Again, my question is simple -- what do we do even if we have troops in the area? Should US troops near the Kurds fire anti-aircraft missiles at any Turkish aircraft that are bombing Kurd held areas?
