South Korea lost billions of dollars because China retaliated South Korea for THAAD. 

Now South Korea is stabbed on its back by Trump who is asking for money that the US owns and decided to deploy own its own.

Hilarious!   I can not find any word for how I feel. 

Take THAAD back trump!    South Koreans do not want it anyway.   They want to develop Nuclear weapon, which is becoming a clear choice for them in light Trump's flip flop.
