S. Korea fires warning shots at disputed border

On Wednesday, the South Korean navy shot 10 warning bullets at a North Korean fishing boat, who crossed the disputed border of theses two countries. The boat stayed in the area about two hours before heading back to its own country. This border has created some problems since the U.N. placed it between the countries. Three skirmishes have been fought there since then. These warning shots were the first to be fired since about 7 years ago.
I think that warning shots from South Korea is a little extreme considering they both have issues with each other. Actions like this will only infuriate North Korea and cause even more, serious problems. I think that these two countries should be happy with what they have and stay within their own borders to prevent further problems.
