Will we tackle Iran and perhaps even North Korea next? Why or why not?

Doubt it.. well maybe Iran.. but their citizens are about ready to revolt and we won't mess with that.. but north korea has thousands or artilliary pieces aimed at soeul - so not happening in that neck of the woods.. Their government will collapse because the people are starving from famine - unless china comes to the rescue.. or American's decide that the better good is served if we give them some food.. It's kind of like seeing your neighbor.. the worst parents ever.. and the worst neighbors ever.. get in trouble with the law.. you still feed and take care of the poor kids.
