That is the conclusion of Narang and Panda in the Times:
North Korea has arrived as a nuclear power, and there is no going back. Once the reality-show theatrics of the Singapore summit meeting subside, we are left with the reality that North Korea was just recognized as a de facto nuclear weapons power.
…. Didn’t he just agree to “work towards complete denuclearization of the Korean Peninsula”? He did. Just like his grandfather’s deputies did in 1993. That phrase — “denuclearization of the Korean Peninsula” — is a term of art that the United States and North Korea can interpret to suit their interests.
Any normalization of relations or easing of sanctions with North Korea will have implications for a number of African states (see here and here) that have enjoyed lucrative economic ties with Pyongyang (mostly through the import of arms and statues).
Namibian officials describe a different North Korea — a longtime ally, a partner in development and an affordable contractor. Since the 1960s, when North Korea began providing support for African nations during their independence struggles with European colonial powers, the regime has fostered political ties on the continent that have turned into commercial relationships.
Recall that it is China that was willing to come to the aid of landlocked Zambia after apartheid South Africa and apartheid-lite Southern Rhodesia threatened the country’s trade links on account of its support for nationalists from both countries. The USSR and Cuba were also vital allies of African nationalist liberation movements at a time when the West was mired in doublespeak over decolonization and racial equality on the Continent. Cuba, in particular, committed blood and treasure in the liberation of Angola and Southwest Africa (Namibia).
Nelson Mandela vowed never to forget friends that aided the ANC against apartheid:
All to say that China, Russia, Cuba, and North Korea are not merely using African states. It has always been a game played on the basis of mutual interests, with the distribution of benefits dictated by the prevailing balance of bargaining power.
