SANCTIONS AND BULLY STATES
When North Korea starting developing a nuclear weapon in secret, spy satellites picked up the activity and alerted the world that a rogue nation with a 3rd rate military was about to become more dangerous. It was decided that, rather than destroy the facilities, negotiations, handouts and sanctions would bring the Koreans to their senses. We alternately blustered, gave them aid, withheld aid, and passed sanctions. Their fanatic, communist leadership alternately, denied the existence of weapons ( or nuclear programs), threatened to use them, stalled at negations, accepted aid, and willingly starved hundreds of thousands of their citizens when aid was withheld. Today they not only possess nuclear weapons, they sell the technology to other rogue nations, such as Syria.
What have we learned? Apparently, nothing. Iran has followed the same track for a decade. Their leadership is even more ideologically fanatic than the Reds. Nothing is more intractable than religious zealots who claim a divine right to rule or destroy any who fail to follow their path. They hate us, have sworn to destroy Israel, have used negotiations to stall action. They do not believe we have the will to stop them. We may not. Israel does.
