As the endgame for America’s nuclear negotiations with Iran looms, I hope that Washington is paying attention to the critical flaws in both its failed agreements with North Korea and the ineffective sanctions imposed on the country in response. I wrote in last month’s issue how Pyongyang has constantly outwitted the United States over the past two decades because the sole goal of the regime is to stay in power, and it therefore will do everything possible to buy time, hug the Americans close, undercut its commitments, and the like.

Now comes news of yet another way that North Korea has evaded U.N.-imposed sanctions, by renaming and transferring the ownership of vessels of a shipping company targeted for illicit arms shipments. None of this should be a surprise, but it is further proof that sanctions are an imperfect tool, at best. Washington has repeatedly turned to sanctions as a way to express its displeasure with Pyongyang and in the hopes of putting enough pressure on the regime that it will eventually return to the negotiating table. With clear acquiescence, if not actual help, from China and Russia, among others, North Korea has been able to avoid serious repercussions for its actions and flout the international community.

The ingenuity of the Kim regime in finding ways around sanctions should be the primary case study for any future sanctions policy. Yet even as more information is made public about its continuing illicit activities, the Obama administration appears to be flirting with going down the primrose path of considering yet more negotiations. In this case, envoys of the White House have been holding talks with representatives from the North about having “talks about talks,” according to the Washington Post. “We want to test if they have an interest in resuming negotiations,” the Post reported an American official saying just this month. The North Koreans undoubtedly would welcome more talks, as that simply gives them more time to perfect their nuclear and ballistic-missile technology. With Washington caught in a dialogue dependency trap, unable to think outside the box and hoping against all experience for an outcome different from last time, expect more evasion and bad faith agreements in the future.
