Korea

Everybody is in jubilation about "peace" on the Korean peninsula.  North Korea is finally seeing the light is what they all want us to think. 

South Korea has been an ally of ours for decades now.  Yes.  Everybody put down your arms and breathe. 

Not so fast.

North Korea has a very disciplined army and will die for their leader.  The terrain is mountainous and dangerous, which makes ground combat very difficult.  The only way to "win" a war with North Korea would be to nuke them.  I can hear the roar out there from you all.  "So what?"

Here's the problem.

We can't nuke North Korea without South Korea getting caught in the crossfire.  If we bomb North Korea, we bomb South Korea because of geographical reality.  South Korea becomes a casualty.  Our atom bombs are not smart enough to cut out and spare South Korea, our allies.  

Both South Korea and North Korea know this.  They are forming an allegiance for fear of us, not because they woke up one morning deciding to finally get along. 

Blood is thicker than water.  Watch out.  This is a grand display.
