I've seen a bit of twitter chatter from international relations people about this article. Most of them are fairly dismissive of Mearshiemer's position---I've seen the phrase "stuck in the 1815 world" of colonial powers used repeatedly.

One that I haven't seen much about in the nuclear non-proliferation issue: if the existence of a country without nukes is predicated on the whims of one with them, every country is strongly incentivized to develop them. As for me, a little bit of my heart belongs to his book, Liddell Hart and the Weight of History.
