Japan should be nervous.
I don’t know. Several years back a prominent Japanese physicist was asked how long it would take for them to start producing nuclear warheads, if they decided to.
The answer was something along the lines of “if we’re told on Monday, then the first one by Thursday. Or maybe Friday.
Now that might just be bluster, but any reasonable analysis says the Japanese can have warheads in a timespan messured in weeks, not months.
THAT would pretty much make every other country in the region flip out. No one wants Japan to have nukes. But the ChiComs are going to assume the Japanese are bluffing, when they’re really playing chicken. I actually think we can trust Obama and Kerry on this ..
