When will we see the end of nuclear deterrance (MAD)?

[Vod]

Since the US copied the former USSR ballistic missile technology in 1960, the world has lived under the threat of Mutually Assured Destruction (MAD).  I remember growing up in the 70s on a farm outside of Edmonton, AB and I would constantly worry about a nuke over the oil processing areas.   No leader has has the insanity AND support to launch a nuke because it would mean the destruction of your own country.

Today both the US and China have their own ballistic defense systems under development.  The US is going with a centralized multi‑layered missile defense (Golden Dome), while China has concentrated on regional and naval ABM interceptors.  The US just announced theirs last year so it won't be ready before 2030.  It also relies on very vulnerable satellites.  However, China has been developing since 2018 and is very secretive - with their manufacturing might and decentralized nature, these systems could surround China before their 2027 invasion.   If China has such a system, announcing it will end the status quo of superpowers.  Stockpiling nukes will be banned... along with the existing US arsenal. 

Remember all the alien movies where they save a violent humanity by removing the ability for war?    When do you think China will end MAD?
