History repeats itself. There was a time when the US had a similar treaty with North Korea. At the instigation of the neocons - George W Bush (the last moron to occupy the oval office) tore up the agreement even though North Korea was in full compliance. Remember Bush's Canadian neocon speech writer - David Frum - labeled North Korea as part of the "Axis of evil".  Had Bush not torn up the agreement we might not be in the situation we are in with North Korea. 

And why did the neocon's want to target North Korea? Because North Korea is an ally of Iran - Israel's arch enemy. So we can see every American foreign policy is made based on what Israel want's - not was is good for America. As a result 10,000's of American's have died in the ME and over a million Muslim's killed thanks to US neocon intervention .
