NORTH KOREA SANCTIONS: Historical amnesia or usual Ignorance?

Prior to the entry of America into World War ll with the Pearl Harbor attack the USA was sanctioning Imperial Japan for it's brutal invasion of China by stopping all scrap metal exports to that country.  Possibly the US sanctions angered Imperial Japan enough to cause their brazen attack on Pearl Harbor?  If Trump administration is aware of this are they hoping to provoke a repeat of this cause and effect event by squeezing Pyongyang so hard and so often that their desperate and irritable regime will launch some sort of attack on the US mainland, Hawaii, Guam or S. Korea so that the US can then justify an all out attack and invasion of North Korea?  Trump's claim that "the Kim regime will be utterly destroyed" may or may not have considered the likely hood that the Kim regime elite have bunkers buried deeply below it's mountainous terrain but also that the increasingly demoralized North Korean Army and population might actively HELP our invasion if it's done intelligently.  As recent military defections increase in numbers, possibly the most effective thing to "drop" behind the DMZ might be "HAPPY MEALS" rather than nukes!
