The Tamil Tigers are now saying that he is still alive. I hope the government can come up with his corpse to prove it is a lie.
It includes video footing showing the body of Prabhakaran, which looks convincing. They also show his dog tags, labeled 0:01.
I think that he is dead, most definitely. But perhaps there will be a myth about his survival, as there was for Hitler. Perhaps people will report seeing him walking around, or having tea at a cafe in Argentina.
