We have a new hyper-sonic missile under development but it looks like we have no effective countermeasure.
We used to be told that WWIII would last over thirty minutes.
Not it looks like they've got it down to under ten.
The future is so bright we're all going to have to start wearing shades.
I would think the more than a few Boomers off their coasts with up to 192 mach 24 trident II warheads and a 7,000 mile range may keep them worried.
