Quoting a south Korean media which recently carried a secret document worked out and presented to U.S. air force university in 1997 by the then active-duty U.S. senior lieutenant, the paper said: The treatise-like document revealed the pollution in the U.S. military bases in south Korea including those in Waegwan, Puphyong, Uijongbu, Chunchon, Tongduchon, Phyongthaek in relative details.

More than 90 U.S. military bases exist in south Korea. This number speaks well for the U.S. forces' environmental pollution turning whole of south Korea to wasteland, the commentary says.

"The serious environmental pollution in south Korea is a product of the U.S. policy of discrimination and extreme contempt for the Korean nation. The U.S. regards south Korea as its colony and an advance base for a new war even though it calls it an ally, the paper added.

The U.S. does not care whether the people of south Korea are contaminated by poisonous chemicals, its mountains and rivers have got dried up and its land turn barren. It finds the value of south Korea only in its role in realizing U.S. Asia strategy, the paper noted.

There are many U.S. military bases in the world but it is only the U.S. forces in south Korea who run roughshod over, exercising extraterritorial privilege, the commentary said, adding:

The U.S. is now working, forming a "joint investigation group" and conducting investigation. But it is clear it would not reveal the whole story as it considers south Korea just as a colony and a war servant.
