I'll trade you a nuke

Today North Korea proclaimed itself a nuclear power and
made demands that U.N. sanctions against it be lifted and
also that they be provided with a light water nuclear power
reactor.

If you're the U.N. or Washington, how can you give in to these
demands? You give them the reactor and they dismantle
their warheads. Next year, they'll restart the nuclear program
again and demand HBO and all the stray dogs in our pounds.

The thing that puzzles me is, is it that much more difficult to
build a "nuclear power reactor" than it is to build a nuclear
weapon?
