don't know this person but sounds quit believable
we have 40 minutes for ICBMs to reach USA Canada from Russia
over the North Pole
15 minutes maybe till detected by satellites
of course must be even less then that if submarine launched
about enough time to gather your loved ones in the house and get to basement
and pray before we die.
no need to worry
General Keane ( who I like but he keeps being wrong) says Putin would never do such.a thing because he knows the consequences
so I will not worry .......

How does a nuclear attack work?
It takes around thirty minutes from Russian missile fields, over the North Pole, reentering the atmosphere over Canada before arriving at US Targets
US satellites would detect the infrared from the exhaust plumes of the missile’s boost phase within ten to fifteen seconds
NORAD uses a double detection system of verification, so a few more seconds go by while, for example, telemetry from the climbing missile is detected
Then it will appear as a “Launch detection” and the response will occur. The President will be informed of the size of the incoming strike package and can issue orders to strike back
This probably takes around fifteen minutes
In the meantime, the Russian ICBM had left the atmosphere, discarded its nose cone and released its warhead “Bus”, a carrier for the MIRVs that sit on it. This will have made some minor course corrections depending upon its programmed targets and is now cruising silently over the Arctic ice cap
Some twenty five minutes after launch was detected, the Bus arrives over Northern Canada. Small rockets fire to orient it at different targets and, at each point, a MIRV is released. The now empty Bus then tries to make a nuisance of itself by ejecting decoys and trying to spoof detection systems
With only a few minutes to go, each MIRV, glowing hot from reentry and decelerating from air friction is making its way over the Great Lakes and into US airspace
Down below, there is frantic activity, some are trying to flee, some to hunker down behind whatever protection they can find. But thirty minutes isn’t really that long at all. Perhaps the husband is trying to get back to his family from work, perhaps the wife was round at her mother’s, perhaps the kids are at school
Once the MIRV reaches around 5000 meters over its intended target, it detonates with around a 550 kiloton yield from the thermonuclear device inside
The flash will blind anyone who looks directly at it and at close range, within a kilometer, prompt X-Rays will vaporize anything that has a water content. Humans are mostly water.
An expanding blast wave will completely flatten every building within two kilometers, substantially damage any out to five kilometers and blow out windows up to ten kilometers away. The PSI overpressure will crush the air spaces inside humans within two kilometers, bringing death from ruptured lungs and compressive trauma. Further out, people will survive with ruptured eardrums
Far more deadly however will be the radiated heat from the rising fireball. Anything that heat “Shines” upon will be burnt. Anything that has a line of sight to the fireball will be heated. A few thousand degrees near the epicenter, dropping as distance increases but still giving third degree burns at five kilometers to unprotected skin
Remember the fireball is rising so the higher it gets the more the area it affects and the less you csn be safe hiding behind a wall or in a ditch for example
Forget about fallout. Since the fireball didn’t touch the ground and was an airburst, no surface material was sucked up to fall down later, irradiated
The danger from radiation is from direct gamma and x-rays absorbed from the initial prompt radiation. You should be safe in one to two weeks
However, you are now alone. No paramedics will come to treat your injuries from burns or flying debris. No Fire Department will come to extinguish your burning house. There is no water, no electricity, only the supplies you have with you. And you have to stay there for two weeks
Now if you live near a national command location, Cheyenne Mountain or a Presidential bunker, you are in far greater trouble. Expect, instead of ten MIRVs on that missile, there to be a single 27 megaton warhead, fuzed for groundburst, with a hardened penetrator on it to “Dig out” the bunker. Expect lethal effects forty kilometers away and you definitely will be getting fallout downwind
That is the reality of a nuclear attack
