Many world leaders say North Korea cannot have nuclear weapons.
But what are they going to do ? Are they going to invade the country ?
Bomb the heck out of it ? Cease trade entirely, and hope they don't continue ?
If a country wants nuclear weapons, they will try and build them. That means
the only real solution is - invade. And that is not going to happen.
The world leaders will continue to talk - but they have no solution.
