If you lived in North Korea, you might think your government had attacked a U.S. aircraft carrier which was approaching the country. You would probably think North Korea had the capabilities to hold their own against the U.S. including “super mighty” preemptive nuclear strikes which could hit mainland USA.
But we live in America, so we believe that North Korea is a backward communist country where the people are oppressed by their government and starving in the streets. Their leader is an insane dictator who talks a big game while the country sits on the brink of collapse.
And this might be close to the truth. We don’t really know though because all of our information about North Korea is imparted to us from the media and our corrupt government which controls them. In that sense, what we know about the world is not so different from what North Koreans know about the world. It is really just a matter of degree.
