We need to quit sending money to NK and other members of the AXIS OF EVIL, and use it to buy our country back from CHINA.
NK has nothing that the world wants or can use with the small exception of conventional weapons and it is restricted in that area.
They are starving all year long and freezing to death in the winter. The only chip they have with which to bargain is the threat of war.
They throw a stone and break a window in the giant's house, knowing that the giant is too benevolent to just squash them.The giant finds it easier and ultimately wiser to just pay them five bucks not to do it again. That keeps things quiet for a bit but sooner or later they need to get the giant's attention again. So they throw a bigger rock, get paid and go sit in the corner of the global yard again.
The problem is that in order to continue to get paid they feel the need to throw bigger and bigger rocks, each time running the risk of exhausting the giant's patience. Yesterday's artillery attack was akin to racheting things up a notch by setting fire to the giant's tool shed instead of breaking another window.
If the giant goes on a controlled rampage against the firebug the whole neighborhood suffers. The option is to wait the firebug/stone-thrower out. Eventually he will get sick and die. That is considered to be the more acceptable option in terms of the cost in lives and fortune, even if it is less satisfying on a gut level.
