Nuclear weapons are the most devastating weapons ever created. 1 bomb has the potential to extinguish hundreds of thousands of lives, and raze an entire city. The threat of nuclear armageddon was most pronounced during the ideological struggle of the Cold War, and the ultimate battle between Communism and Capitalism. In this period, thousands of nuclear bombs were produced, and never used.
After the collapse of the USSR in 1991, many viewed the threat to be over. America really no longer had a need to continue keeping nuclear weapons, yet we did. Regardless of the fact that nuclear stockpiles have decreased by 2/3rds since the end of the Cold War, there are still around 15,375 nuclear warheads in existence, Russia and the US owning 93% of them. Other nuclear powers include France, China, the UK, India, Pakistan, Israel, and North Korea.
However, I would argue that the threat of a nuclear attack is not just probable, it is inevitable on the path that we are taking as a global community. Not an attack by organized nations, rather an attack by a terrorist group, or just any non-state group. The ease in which nuclear weapons can be produced is astounding, and it highlights why nuclear non-proliferation should be the ultimate goal of any nation.
The nuclear arsenal of the US is aging, not very well-secured, and dangerous, however this pales in comparison to the risk emanating from Russia and the former Soviet Union. These areas of the world are highly unstable and corrupt, and there is a threat of a government official selling a nuclear warhead to the highest bidder
On top of all of this, President Trump is highly unstable, and will most likely be unwilling to decrease the size of the US nuclear stockpile, and President Putin is unlikely to do that either.
The longer that we retain control of such vast stockpiles, the more likely it is that eventually they will be used in some way. Nuclear weapons are perhaps the largest threat to our societies in this day and age, and their importance must not be ignored. The ease in which terrorists could manufacture or obtain a nuclear weapon is not negligible.
In this time of great instability, it is imperative that the global community commits to nuclear non-proliferation, with the eventual goal of a nuclear-free Earth. The threat of mass death and destruction is too high for a weapon that no state would ever dare use.
