I suspect the Japanese could produce a native nuclear weapon within 30 days of the go order.
Or by the time you finish reading this post. They probably have all the components built, tested and sitting no further than 6" apart from each other awaiting assembly, and has probably been the case for decades.
No doubt. Ditto SK.
“I suspect the Japanese could produce a native nuclear weapon within 30 days of the go order.”
I suspect that they’re more likely just to go public with the fact that they’ve secretly had nukes for several years now. Not that I know that they have nukes, it’s just that I can’t imagine Japan NOT having nukes somewhere.
