If we DO decide to take action against him (doubtful ) which seems most humane and cost effective ? A quick invasion like Panama or Grenada, Bombing raids as in Kosavo and Libya, or assassinating HIM.
Sounds like a time to run a few "El Presidente" drills with live targets......now who could serve as the other two targets? 
Any ideas TomB? 
I'll agree to Sean Penn, but I nominate George Clooney for the third slot. I would have said Pelosi but the bullets might release the Botox and the stored energy from all those face lifts.
