While people are panicking about what North Korea is going to do. My thing is this, if they had the capability to strike why give a warning. This is just to distract the people from other issues. Plus North Korea don't really want no smoke man that's just all talk. What I don't understand about the ownership of such weapons by any country. Why have the ability to cause mass destruction that will even affect the ones using it. There is no way a nuclear missile is going to be fired and it not disrupt the universe as a whole.
I feel many weapons of war are coward tools these days. Whereas back in the day, the battlefield was where hand to hand combat took place. Now countries are using robots and unmanned vehicles to win the war. Just ain't the same psychological process.
