Should we send ground forces to aid the US-trained Syrian rebels in their fight against ISIS?

The government has been training moderate Syrian rebels to fight against ISIS, but the number of rebels they have trained is significantly lower than expected - as in 60. Earlier this week, it was confirmed that a group connected to al-Quaeda has kidnapped five of the rebels. Obama has realized that the Syrian rebels are in need of aid, and has approved providing air support for the Free Syrian forces.

Do you think that we should be doing more to help the Syrian rebels fight against ISIS?
