The demolition of the WTC was thermonuclear. TPTB knew this. 9/11 first responders and NYC residents did not.
Everyone on-site was inhaling not just asbestos, but *irradiated* asbestos that stuck in their lungs, well, more or less forever. So they were exposed to that radiation not just for a few hours, but for its entire decay cycle... from the inside out. (The original plan was to blow the bridges, so thousands more Manhattan residents would have been stuck on that island breathing that dust for days.)
When they got sick, and developed all manner of radiogenic cancers (
https://www.vcf.gov/pdf/CancerlistingFinal.pdf), a special emergency Victims Compensation Program was used to cover up the true cause of their cancer. The press provided the rest of the cover. Nobody ever found out beyond "toxic dust". Simple, cheap iodine tablets could have prevent so much suffering, but that would have revealed the secret. (Our guys, the CIA and bankers and such, were coerced into keeping the secret because they believed letting the public know that Al Quaeda or Bin Laden or Saudi Arabia was able to nuke Wall Street would crash the economy. It was Israel, of course.)
This was a small scale test, a dress rehearsal to see if their could use the medical system and press to hide the cause of these cancers from the public and from the victims themselves -- that is, treat them with chemotherapy, radiation, surgery, and countless other pharmaceuticals. They could. So the plan was rolled to the rest of the country.
Cancer is being deliberately induced into the population by every mechanism possible. Soon, 50% of us will contract some form of cancer during our lifetimes. Very few people in the US have not been touched by It. Because it is so epidemic, it is seen as normal, practically expected.
From a business perspective: At an average cost of over $150k per person, cancer is perhaps the most profitable way to quietly genocide a population.
