Can you detail to me the number of Countries North Korea has attacked because they deemed them as a threat to their security?
Can you contrast that to the United States of America ?
How many people died to Saddam Hussein and his Iraq whio by the way GOT that poison gas by the "rational" United States of America? Contrast that to that "Rational" USA and its bombing of Libya, Syria, Pakistan, Afgnainstan, Iraq, Yemen and countries too numerous to mention because they CLAIM these countries a grave threat.
I am far more worried about the USA having Nuclear weapons, given they they the only country on this earth that had leaders so irrational they would drop them on cities than I am with North Korea having a missile that can launch a satellite into space even if the attached a nuclear weapon to it. The language of the leader of North Korea in deeming himself as exceptional is no different than that of the leader of the United States of America when he claims the USA exceptional over all other nations and the worlds indispensable nation.
The USA and its Military tries to foment a war with Russia. THAT is irrational and THAT is dangerous.
