That is a beautiful treaty for any nation to take comfort in, and to give hope and stability in a crisis such as this pandemic whereas, the weakening of any nation would not have to befall to the contingent of engaging in a war or a nation stockpiling nuclear warheads.
However, has anyone paid attention to the other four nations (Israel, India, Pakistan and North Korea) who own nuclear weapons and these nations are not a part of the Nuclear Non-Proliferation Treaty (NPT) and each has remained to keep storing, making, testing, or buying nuclear weaponry from neighboring countries.
Kim Jong Un of North Korea, the successor of his late father, Kim Jong-il, who was never strong allies to enter into any peaceful long-term resolution or resolve silent nuclear threats against America or retain its stronghold on our democracy as far as consumerism; tariffs of export/import tax breaks
In addition, the last I heard, Kim Jong Un has made it his priority to engage in high-tech weapons to respond to the instability on the Korean Peninsula.
I do hope somewhere in time these other nations will take that peaceful oath, but I seriously doubt it.. nevertheless, one can only hope
