The fact that the US can find only 60 Syrian rebels to train is quite telling.
It means that out of nearly 18 million Syrians (reduced by 4 million since the start of the conflict) the US could only find 60 that were willing to fight against the Syrian Army, only 60. [1]
In other words, only an increase of ~0.000333% of the Syrian population is deemed “moderate” by the US and willing to fight. The military is currently in the process of vetting 7,000 volunteers so, if we assume that all of them will pass inspection, that will amount to a mere ~0.039222% of the population. A far cry from 0.1%, let alone 1% of the total inhabitants.
The fact that only 60 can be deemed “moderate” is also quite telling. This coming from a government who deemed the Free Syrian Army, among others, as “moderates.”
