A Korean-American, Ms. Eun Mi Shin is praising North Korea which is a cruel rouge group which tortures and kills their people, which is building nuclear bomb and missiles to attack U.S., and which killed over 50,000 American young soldiers during Korean War.
She is having talk shows in S. Korea to praise N. Korea dictator and trying to deceive S. Korean people.
Shin is definitely violating the crucial obligation of U.S. Citizenship Oath by praising the enemy of U.S.A. So, there must have been evident reason for U.S. government to consider revoking her citizenship.
S. Korea government is in very awkward situation now, because they should arrest her immediately due to treason and violating Korean Constitution and laws but due to the close relationship with U.S. government, they can't do.
