How to know if President Obama has ordered covert actions against Assad

Like I said the other day, I expect that even if Congress declines to
authorize the use of military force in Syria, President Obama will order a
variety of covert actions in support of the rebels.

How can we know if these are occurring?
Basically, I think we should look for things happening that the rebels would have
liked to do a long time ago but were unable to carry out. For example,
assassinations of senior Syrian officials. I could see, for example, stealthy
drone attacks on the convoys of the officials who oversaw the use of chemical
weapons -- but credit being given to Syrian rebels. I also think we could see
things like signals intercepts being passed to the rebels, as well as other
helpful intelligence, like real-time satellite imagery. Basically, any
anomalous action bears a second look.

Fast transmission of targeting info
could significantly boost the effectiveness of the opposition, I think. I've
been told that, during the Iran-Iraq War, the U.S. provided Saddam Hussein's
air force with good photo imagery of Iranian military targets, such as major
supply depots and corps-level headquarters, and that the subsequent Iraqi airstrikes
broke an Iranian offensive and so changed the balance of the war.

Yet even as I discuss this, I wonder:
If the rebels win, how will they treat Armenians, Jews, Christians, and other
minorities?
