There are calls from within the U.S. Congress to put North Korea back on a blacklist of states sponsoring terrorism after the sinking of South Korean Navy corvette Cheonan. Radio Free Asia, citing a Congress official, said members are pushing for a bill or resolution to list North Korea again.
Republican Congressmen have already discussed the matter. Another persuasive piece of evidence will be a recently foiled assassination attempt on the former secretary of the North Korean Workers' Party Hwang Jang-yop, who defected to the South in 1997.
Republican Representative Eric Cantor said if North Korea was involved in the sinking of Cheonan, then Congress should take the necessary steps.
The South Korean Embassy in Washington believes that as soon as the investigation of sinking is complete, there will be movement in Congress to put North Korea back on the list.
