There is no reason to believe that, as a result of the deal Iran is already sidestepping, Iran will suddenly stop all dealings with North Korea with regard to both countries’ nuclear programs
North Korea conducted its fourth nuclear test on January 6th, which it claimed was a hydrogen bomb. Despite some skepticism as to North Korea’s claim that it had actually tested a hydrogen bomb, the Obama administration acknowledged that North Korea had indeed tested some sort of nuclear device. The administration condemned North Korea’s latest testing as a violation of a series of past United Nations Security Council resolutions.
"We do not and will not accept North Korea as a nuclear armed state, and actions such as this latest test only strengthen our resolve," declared Secretary of State John Kerry.
