Detecting launch prep might be useful but it's ultimately just too easy to conceal a launch site to be the complete solution. It doesn't really help with a sneak attack from a major power and US missile defense isn't even good enough yet to reliably stop a NK attack.
What the world really needs is to ensure mutually assured destruction is remains in effect. The world cannot afford to let the Russian or Chinese dictators believe they can pull off a first strike and take over the world.
The problem right now is that the US is still trying to uphold MAD by itself and it's failing. The US nuclear triad is way out of date and potentially vulnerable to a first strike. We need to decentralize the system among other wealthy and trustworthy countries.
All countries in the G7 should have enough nuclear weapons pointed at Russia and China to ensure MAD. And they should develop these weapons independently of the US for increased reliability and redundancy.
