Somebody please

I know i shouldn't be surprised, but sometimes i wonder how ignorant people can be!
There are TWO Koreas, North and South! And they are very different...

However there are still many people who doesn't seem to get it.
I can understand that the people in my grandmas age have a problem, back in their younger days there was only ONE Korea.
But since the 1950's there have been two!!

So i found this in today's Metro newspaper - Dennis Rodman tweeted that he might run into "the Gangnam style" guy while he is in NORTH KOREA!
at least Americans should know what country the send soldiers and is their friend and not enemy!!!

Please, what's wrong with todays education? This should be common knowledge!!
