They were caught red-handed while bringing through military mail drugs enough for the simultaneous use by 150 000 people from 2010 to 2014, according to Dong-A Ilbo of south Korea.

The volume of drug introduction has sharply increased each year, reaching 7.7 times as against the year before from January to September, 2012.

It is supposed that substantial introduction of drugs by military mail to the U.S. imperialist aggression forces would be much more than the disclosed as this has been kept secret.

Severity of the problem is that the puppet authorities are not in a position to make a word of protest or put it under control even though they are well aware of the route through which drugs make their way.

The puppet customs agency can neither inspect nor open articles of U.S. military passing through customs counter without intervention by the U.S. military side.

This is the way how the U.S. imperialist aggression forces brought to south Korea dangerous bio-chemical weapons including anthrax.

But the puppet forces seized by sycophancy connive and foster such crimes under shackling agreement like the U.S.-south Korea "Status of Forces Agreement".
