He has pilots already since he's been using them to attack sites in columbia on behalf of FARC. Different aircraft, but he will have people trained for the MiG-29s.

Cuba is a terrorist- backing country we should have taken out a long, long time ago, but couldn't because of folks like Dellums, Harkin, Kerry and Kennedy.
