Russia & China had/has NO PROBLEM with North Korea creating a nuclear arsenal. They also have NO PROBLEM with Iran creating a nuclear arsenal. We should abandon the nuclear non-proliferation agreement because it doesn't work when the world's most nefarious powers are ignoring it. Then, we should encourage Japan and South Korea to develop their own nuclear arsenals. As well, we should do the same with Ukraine and Poland and perhaps others. If we did, or at least threatened to do so, perhaps Russia and China would get on-board with eliminating North Korea's nuclear arsenal and preventing Iran's acquisition of such.
