I thought those were atomic weapons we used against Japan - is there not a difference between little atomic popwads and thermonuclear explosives?

Sure, in terms of yield. They're actually more efficient. See the reference in post 26.

A Hydrogen nuke is certainly the biggest bang for the buck. Hydrogen is what fuels every star in the universe and hydrogen makes things happen like the creation of new stars and along with water and under the right conditions it makes life. But the nukes of 1945 would still do the job. In fact think of one Hiroshima type bomb detonated over Times Square or London or any major city. After the initial blast, the millisecond wherein for thousand of square yards the heat released is many times that of the surface of the sun and the shock wave, panic among the populace would be beyond belief.
