Who exactly IS eligible for Refugee status?

Peters 'exposes' Fakhri Sabri Mohammed as a 'fake' refugee. Mr. Mohammed got into hot water with Saddam's regime for disagreeing with Saddam's treatment of the Kurds.

If Mr. Peters thinks Mr. Mohammed (who rebelled against Saddam's regime) isn't worthy of refugee status.. then that begs the question.. who IS?!?!
