The great thing about North Korea is they are ruled by a whack job idiot, their own leader does more damage to them than we could with carpet bombing. They are broke, starving, have no economic power to wage any kind of challenge to us. Pretty much we can sit back and laugh at them, if need be at some point in the future we'll tactical nuke that regime back to the stone age.
Yes, they are ruled by a "whack job idiot". Not unlike Chairman Mao, Adolph Hitler, Lenin, Mussolini or Stalin. How did that workout? Supreme Leader Kim Jung-un cares not a wit about his people starving. He's murdered his own relatives to assure his place in power.
Experts have said that they fully expect North Korea to have a nuclear ballistic missile capable of reaching our West Coast by the end of President Trump's first term.
That's a problem.
