Hello everyone, This post will focus on explaining how Nuclear arsenals have secured peace and security within nations around the world, and why that's very, very important. If you disagree with any of the points I put across, I encourage some challenging. Nuclear Weapons It is absolutely undeniable that nuclear weapons have ultimately changed warfare since 1945. We have not seen a major war since WW2, with almost all wars since being proxy wars, with the Korean War perhaps being the exception. Nuclear weapons have devastating and phenomenal capability with the most absurd destruction potential. It is no denying that, from 1945 onwards, they shaped our outlook on future major wars. Mutually Assured Destruction (M.A.D) M.A.D is the idea, or rather doctrine, that encompasses why many people - including myself - actually support nuclear expansion, and support the updating of nuclear arsenals. Simplified as much as possible, M.A.D is the idea that "if you hit me, I'll hit you harder" and revolves around the threat of total annihilation. So long as that threat exists, which it does with nuclear arsenals, it is extremely unlikely any other nation would be willing to pick a fight with the other - and vice versa. If you launch all your ICBMs at me, I'll launch all my ICBMs at you, and so on so forth. This doctrine has been adopted by every country with a nuclear arsenal, and has yet to be disproved. Yes, even the DPRK obeys this doctrine. It is human nature within leaders, nobody wants to see themselves and their countries eradicated, even if you take the opposition down with you. It is also a major reason why the DPRK still exists, as due to their nuclear arsenal, no nation wishes to provoke them too much to the point of war, the risk/reward is simply not enough. If the DPRK did not have a nuclear arsenal, it's likely we would've seen Korean War 2.0 with the eventual defeat of the DPRK. Due to their ICBMs and nuclear capability however, nobody wants this. Peace Peace has been secured globally between powerful nations since the end of the second world war, with the majority of wars being proxy wars, it is arguable that mass human casualties and major wars have almost faded out into the history books. Europe has seen everlasting major peace since the second world war, a feat not accomplished before. The Links It is not at all hard to see where the links between M.A.D and peace come from - since the development and successful rise of nuclear arsenals within nations, there has been no major wars. The tensions between the Soviet Union and NATO were high enough to lead to total war; this was averted with the threat of total annihilation. Neither side wants to fire first. As soon as you fire first, you are guaranteed that you will have their entire arsenal coming right back at you, which is not the sort of conflict you can escape, negotiate or deal your way out of. Without nuclear weapons, it is arguable we would still be seeing the previous, traditionalist style of warfare, with men, tanks, planes and bombs. We still have this type of warfare of course, but we would most likely see it on a major scale if it was not for the threat of mutually assured destruction. Perhaps, without nuclear weapons, we would see a return of the previous warfare doctrines, with the stakes not high enough to justify not going to war.
