LAUGHING WOLF HAS THOUGHTS ON DECAPITATION STRIKES: Surprise, Response.
The thirty-minute window was predicated on detecting Soviet missiles being launched. Flight time from there to here is roughly thirty minutes. If we saw them fueling (Soviets/Russians use a lot of liquid-fueled ICBMs), longer period for response. That was sufficient: thirty or forty years ago.
Even twenty years ago, depressed trajectory shots from subs not too far off the coast cut that time from detection to impact to about fifteen minutes. The assurances the subs couldn’t get that close, and would be detected if they did, were deafening, though reminding me a bit of toddlers drumming their feet and yelling while having their fingers in their ears.
Today, we have massive container ships plying the waters of our country. If I can figure how to put one or more land-attack cruise missiles into a container for launch, I guarantee you others have as well. When you look at more modern drones, boy howdy are you talking the ability to get things in the air and to target with little or no detection. Iran has the capability (or did) and China has been openly experimenting with it. For all the open, think iceberg and know others have as well, a lot of others.
We lost our sense of seriousness about these things during the Clinton administration, and never fully got it back.
