North Korea

North Korea is, and will almost certainly remain, a nuclear power.

Kim Jong Mentally Il's totalitarian regime, with its massive human rights violations, is kept afloat almost entirely by massive foreign aid, and China pulls the largest purse string.

"Engaging" N. Korea amounts to little more than appeasement, and keeps this tyrannical regime in power.

The six-party negotiations have produced no results.

N. Korea is a rogue state with nukes and needs to be cut off from Chinese support.

When diplomacy fails, the next step is sanctions.
