This issue is another proof that politic sucks.
it's not about atomic bombs or threats, it's just all about connections (i dont mean internet connections, i mean connections to other countries) and interests.
Let's see how US act:
Iraq:
Iraq was attacked, coz this country was a huge danger for their neigbours and the free world....said the US government.
Hmm pretty handy that Iraq didn't had a close connection to Russia and China. innit?
I guess we all know that the US just wanted the oil. Now after many innocent people were killed. US firms (mainly from Texas) control the iraqi oil fields.
Well done USA
.
North Korea:
North Korea is more dangerous than Iraq ever was. but why the fuck ain't the USA invade this state?
Well, North Korea has/had close connections to China and Russia. That's why NK will never ever have to fear any restrictions from th UN (united nations).
Ontop of that the USA are afraid of China.
yes, pretty simple. And that's why intl. politics are so useless nowadays.
