The burial of defoliant in the Waegwan U.S. military base is not a mere crime, it said.

It is essential to survey all the U.S. military bases in south Korea with this case as a momentum, the commentary said, adding that the south Korea-U.S. SOFA should be revised to prevent such action as burial and crimes by the U.S. troops.

The Headquarters of the Movement for the Withdrawal of the U.S. Forces in south Korea, too, issued a commentary on May 20 in which it called for surveying not only the Waegwan base but also all other U.S. military bases across south Korea and opening to the public the truth about the U.S. forces' crimes.

More serious is the fact that there is suspicion that what the U.S. forces buried in the base might be not only defoliant but nuclear waste, it said.

Different social circles are now strongly demanding a thoroughgoing investigation into the defoliant burial case, according to south Korea's KBS on May 24.
