What is the impact after nuclear test in N. Korea?

according to the impact is more onthe nuclear weapon states.it should be understood that not only the five nations are recognised as nuclear weapons country as they openly show that tahey are but i believe most of the states in the world which are developing adn developed states alredy posses nuclesr waepons .though they haven't test their weapon openly .the impact will be huge though it would be the biggest story of the year.

The action of Communist North Korea in developing Nuclear weapon, will only make democratic south korea to seek support from US. For USA, it is a new customer for Nuclear Arams.

In the present day world its becoming a race of arms. No one is ready to stand back and see others strengtheniong their arsenal. Except I think ordinary citizens like us no govt. is bothered aboput what is it doing to the earth's climate. with depleting ozone layer and increasing earthquakes we will surely end up blowing this world apart some day. Now world's alliance will change pattern for sure, some countries will join hand with US against north korea. Its becoming a pathetic thing to see and watch, we keep thinking now what next and some countries are not that responsble to in their policies. It lookslike a grim future to me.
