All you need to know about the Obama Administration's efforts, impact and effectiveness, in building a separate force on the ground to fight ISIS in Syria is summed up by the recent short comments by the US Secretary of Defense, Ash Carter in front of the US Congress:
Epic fail.
US Air Strikes are having an impact. But the ISIS forces will never be completely defeated and dislodged by that alone...and everyone knew it.
Such a minimal force as the US has created to date will have zero impact on the ground...and everyone knows that too.
No sense at this point, IMHO, even including them in any serious discussion.
Now, US air support for other sizable and effective forces on the ground, like the Turkish forces on the Turkish/Syrian border, or the Kurd forces in Iraq can be very helpful and telling.
If the Iraqi forces raise their game and display the commitment and dedication to gight and win...and not run... air support for them can be very helpful too.
Air support can also strike targets of opportunity and destroy Command and Control when it is found, take out leadership when they are found, and degrade ISIS depots and infrastructure.
But in the end...boots on the ground are going to have to take back territory and ultimately defeat ISIS fighters on the ground. US air support and air support from others can help those forces...but air strikes alone cannot replace them.
Problem is the damn Turks are also bombing the PKK who seems to be the only ones actively fighting ISIS in an effective manner.
