There is no debate that ground troops will be needed in Syria. Whose? When?

Officials at every relevant level of government in the US, and in each of the coalition members, agree that a ground force will be needed in Syria.

Dempsey are spoken on the order of around 15,000. The moderate Syrian rebels we are about to begin training in Saudi Arabia will not be battle ready until this time next year, optimistically. It is also unclear the rate at which the moderate rebels will be trained.

Turkey has now signaled a willingness to deploy ground troops to Syria, but only in a protector role, not primarily combative. Turkey troops would maintain a buffer along its border and guard an expected war refugee camp within Syria. (By the way, this is another indicator that this will be a years to decade length war).

The question is: how long will we continue with the air war alone? We will do solely airstrikes until 15,000 moderate rebels are on the ground? No other country has indicated a willingness to deploy the necessary ground troops into Syria.

When will the request/proposal be made? What nation's troops will be deployed?

And, that is only asking about Syria. In Iraq, the Iraqi Army and the Kurds haven't been able to do it. Even with our air war, they are not doing well. When and how many troops will go to Iraq? And whom?
