Interesting points. My argument was that geography plays as massive a role in geopolitics today as as ever - we just don't see it because it doesn't vary as much in our lifetimes as the more minor components, e.g. cultural factors. Sort of like how stock analysts tend to over-attribute company management for effects of macroeconomic forces.
Given the diversity in geographies and a bounded "sweet spot" for productivity (by presently known means) I would argue that a global event would not have uniform effects on all nations. For example, global warming would devastate the Chinese and Indian breadbaskets while opening up Siberia and Greenland to agriculture.
My usage of a weapon, which being technology would be replicated by others over time, was flawed. Oops =P.
Regarding Israel, I don't think the conclusion from geopolitics is that geography is a limiting factor in a nation's potential. Israel has exploited its human capital expertly. That said, given its present borders it will tend to be a client state of an outside power; its geopolitical situation is highly leveraged in that the loss of American military and economic backing would spell existential chaos for it. Singapore, Taiwan, Luxembourg, et al do very well by this model. But their sovereignty is, at the end of the day, subordinated to an outsider's. Further, not everyone in the world can follow this strategy (it would be too easy for one to start shooting and upset the illusion of stability).
"most of the topsoil" is relative on this context. In Canada and Scandinavia there is nearly no topsoil left compared to regions which haven't gone through repeated glaciations. However what is there is sufficient to grow food. Yes, I am a geologist.
What about northern Siberia? Is there more topsoil there than at similar latitudes in Canada and Scandinavia?
ADDED. I have a tentative answer to my own question: glaciers probably cannot push topsoil over mountains, which is probably why there is farming in Alberta, Canada, at latitudes where there is no farming in Quebec. (The Rockies take a big zap westward there.) Since there are lots of mountains running east-to-west in western Siberia, there are probably regions rich in topsoil north of those mountains, but not in eastern Siberia, and not in the high latitudes of European Russia.
Unless in the regions north of those west-east mountains, the presence of the mountains caused the glaciers to flow from south to north. hmm.
