Obama willing to sell out U.S. troops to South Korean Command, sign of declining U.S. Empire

In an unprecedented move, the United States has agreed, in principal, to put U.S. forces under the direct command of South Korea. Details are still being worked out.

“It is an unprecedented measure since the U.S. military is characteristically reluctant to place troops under the command of other countries.”The Chosun Ilbo, Korean newspaper

Officially the move is to help South Korea in case of attack by North Korea. But isn’t that why our troops are there to begin with? Why do they have to be placed under direct control of the South Koreans?  Never in United States history has another country controlled our military forces! Even the Russians didn’t do that after the fall of the Soviet Union.  Is it another sign of the decline of the U.S. Empire?
