A better question might be "What's not wrong with Huntington's Clash of Civilizations?", but I'll try not to be too pedantic. In light of recent events, interest in Huntington's thesis has been growing. Even the NYTimes is using language that is clearly influenced by Huntington's work, though they don't specifically mention it. So let's review the merits (such as they are) and demerits of this argument.
In a previous post, I introduced a new index of military capabilities, based on data that is already widely in use (see also this Duck of Minerva post). Based on the great feedback I've received, I decided it was time to revise the measure, and to see how well it does in accounting for war outcomes and the likelihood of conflict.
