That has to be one of the most insane things I've heard. First off consider the success at training the Free Syrian Army. Then where will you recruit these soldiers from? Where will they be based? Are they only going to be answerable to the US? Would the US be responsible for mercenaries' human rights abuses? Each point is a logistical, political and diplomatic nightmare.
This is why I said this topic can not be discussed seriously on A2K. This should be about stopping the bombings, practical solutions, not more war in far off lands US by proxy, almost hands off.
What Farmerman had to say about explosives was very illuminating, can we stick to Brussels and Paris and not what we want to do to Syria please?
