Nothing close to an 800 megaton nuke has ever existed.
The B41 was the highest yield of any American weapon ever (retired in1976) - about 25 megatons. The largest Russian weapon was the AN602 “Tsar Bomba” at 50 megatons, but only one was ever officially built, and the actual yield when exploded was more like 15 megatons. These could obliterate major cities, and kill millions upon detonation.
The biggest available to us today is the B83, at about 1.2 megatons at full yield. It is delivered by bomber aircraft, but is not on regular operational status. It would need to pulled from storage. The weapons ready to fire run around one to five hundred kilotons - 8 to 40 times Hiroshima.

Whatever, but thanks for the info ... The point is, we need to make an example out of a few million of these a-holes ... And I guarantee that if we nuked a few of their cities, the Muslim maggots would not only suddenly go silent, but rather quickly their roach-like hoards would crawl back beneath the slime-covered rocks from which they emerged. The only thing these vermin have ever understood, from the very beginning, is full-on unrestrained brute force. History proves that once they get the living crap kicked out of them, they go away, but only for a few generations. That is not sufficient. We need to do unimaginably horrific damage - and on so great a scale that political Islam will regress for a thousand years, if not totally disappear.
