>> An intentionally dirty nuke detonated over a large city can kill millions <<

Ridiculous, absurd, unadulterated nonsense. You obviously not only know not one bloody thing about what you’re writing about, you’re too lazy and/or stupid to validate your own ignorant statements by looking something up on the internet.

>> And you know that it almost went off how? <<

Government documents declassified in 2013 of Parker F Jones, supervisor of nuclear weapons safety at Sandia National Labs, writing on October 22, 1969 criticizing yet concurring with the assessment by Dr. Ralph Lapp, formerly of the Manhattan Project, made in 1962:

“Lapp’s report lacks objectivity and accuracy. His sources of information are patently erroneous, or he chooses to misuse them for his own benefit. But the central point is correctly stated: one single, dynamo-technology switch stood between the United States and a major catastrophe...”

Again... this isn’t even a bomb designed to detonate on impact; this was a bomb designed to detonate in the air, which almost spontaneously detonated on the ground.

[Garth Tater]

The bomb that "almost" exploded descended on it's parachute. It did not hit the ground (or the water in this case) at terminal velocity.

Wikipedia:

"Three of the four arming mechanisms on one of the bombs activated, causing it to execute many of the steps needed to arm itself, such as charging the firing capacitors and, critically, deployment of a 100-foot-diameter (30 m) retard parachute. The parachute allowed that bomb to hit the ground with little damage."

So, to prove me wrong when I said your scenario of a nuclear armed missile detonating on impact was bullhockey you gave an an example of a nuclear weapon descending under its parachute... Are you about ready to give up yet?
