Mahalo Tulsi for continuing to question authority, and challenge flawed conventional thinking.  Arming "moderate rebels" to force regime change didn't work in Cuba '61 or Nicaragua '85.  Afgahnistan '79 gave rise to Bin Laden.  Removing Saddam unleashed a Pandora's box that spawned ISIS, and removing the brutal dictator Ghadaffi created an unstable terrorist safe haven that now requires our periodic bombing (which also kills civilians, ahem...)  Will the triangulating neocons on the Left ever learn?
