EU vs Un

As Kim Jong-un test fires another nuke, the EU tightens the pretend screws:

EU finance ministers, condemning the Feb. 12 nuclear test by North Korea, have imposed trade and economic sanctions on the Asian nation.

A statement by the 27 European Union finance ministers, who met Monday in Brussels, said they condemn the test "in the strongest terms" and demand that North Korea abstain from further tests. The statement also urged North Korea to sign the Comprehensive Nuclear Test Ban Treaty without delay.

I'm not about to argue in favor of free trade with a criminal state like North Korea. But what is the point of endless rounds of new sanctions, when the old ones haven't forced the DPRK to change its evil ways?
