Hiroshima is not still radioactive in a way that poses a health risk to its residents. The radiation levels in Hiroshima are now comparable to the natural background radiation found anywhere else on Earth.

Hiroshima wasn't detonated at ground level though. Detonation occurred nearly 2000 feet above ground level.

I thought she said in the interview with Lex Fridman that we have a satellite that can immediately detect this. Then the clock begins ticking for the President to decide WTF to do.


I haven't seen the interview. But from the book, as I recall, we can detect an ICBM launch in near-real time from pretty much anywhere. But at one point in the fictionalized part of the book one of the DOD guys asks if we can confirm the warheads are nuclear and they're told they can't.

Now, I assume that for a lot of nuclear states we know what they have and where and can draw a lot of inferences from other intelligence, but my takeaway was that if someone went through the hassle of launching a conventional warhead ICBM, we wouldn't know and would likely respond with a nuclear salvo.

I also asked Grok, who in relevant part said:

While research into advanced sensor technologies (e.g., hyperspectral imaging, advanced radar, or AI-enhanced data analysis) continues, no publicly disclosed systems as of my knowledge cutoff in 2023 can reliably differentiate between nuclear and conventional warheads in flight. This limitation is a significant challenge in strategic defense planning, as it forces nations to assume the worst-case scenario (i.e., a nuclear payload) when responding to an ICBM launch, potentially escalating conflicts.

They want Israel gone, as in the people, but they do not want the land uninhabitable......they want the riches left in place.


Amazing.

Israel is approximately 8600 square miles, can't imagine that little bit of land has a lot of "riches"......what it does have is historic religious significance to Muslims, Jews and Christians.

My fear, and it has been a fear for +40 years is the potential for a suitcase nuke or some form of small scale nuke being smuggled into an area and detonated, I don't think it would be an impossible task for a terroristic nation to pull this off.
We had two planes flown into the World Trade Center, and one into the fricking Pentagon. The shitbirds that did it, came her under student visas. If that can happen, then a briefcase dirty bomb is very plausible.

I wonder how light rain knocks out Nola power yet Israel still has power with all those rockets.

Teedy. Get over there now and figure that out. Get what they they have to replace entergy

That’s where Jewish nation might be in big trouble. About how high do those dome defenses intercept? Doesn’t look terribly high.

The modern day cities of Hiroshima and Nagasaki, Japan are built on the same sites that were nuked in 1945.

And, again, my comment was talking about a nuke at ground level carried out by a terrorist. Not a nuke detonated at altitude on a delivery system.

There is a huge difference in radiation dissipation when a a nuke is detonated in the air vs. when one is detonated on the ground. Both Hiroshima and Nagasaki were air detonations. The US knew that detonating at ground level would make parts of Japan completely uninhabitable for thousands of years, and that's one of the reasons (aside from greater damage) that we detonated the bombs at 3/8ths of a mile high.

What about the Los Alamos test site? The bomb was dropped from a tower that was certainly less than 3/8 of a mile high. It's probably off limits for all sorts of reasons, but is it uninhabitable?

A nuclear meltdown or a dirty bomb is a different thing. It produces all sorts of fission products, but a bomb turns a lot more of its fissionable fuel into energy.

I agree that a ground burst creates nastier local fallout because some of the radioactive particles adhere to dust and dirt and fallout locally plus get blown up into the atmosphere and spread by the winds, but the hundreds of thousands of years, even though some fission products do last that long, sounds excessive. People live near the bikini atoll site today and we detonated how many devices there in the post war era?
