"It has been a brutal few months for South Korean Americans in U.S.,"

Who had to endure having seen some historical brutality in their motherland.

Nothing much we could have done. Anyway, let's just have a fun.

It's a small world. People and businesses learn fast on what happened in South Korea.

The united Airlines decided to imitate (?) what the Koreans had done to their president in South Korea.

Believe or not, after very similar thing had happened in South Korea at the presidential palace.

Not to be outdone, they had done the same thing to one of their paying passengers in the United flight.
