For over the past years some people who reside in the United States implement their political agendas to spread out.Those are the issues not related to U.S..
For example,"Dokdo belongs to us" which adverted in the Times Square in New York City.Or the statue which placed in Glendale,California saying this is the monument of carnal thralls during WW2 by Japanese Army.
Sadly some people do kinds of such things in,where nothing has to do with the U.S..
This may lead to unnecessary hostile atmospheres among the ethnic groups who reside in the U.S.which,may result in hate.
Thereby I suggest Obama administration to illegalize any foreign political issues,including controversial historical topics to bring within the U.S. soil.
