Ilan Goldenberg writes the most cogent analysis of paths out of the Iraq debacle you’ll find. Read the whole thing, but the concluding nugget is here:
Bottom line: I have yet to find an expert on Middle East politics who thinks that the “bottom up” strategy has any real chance of success. The only people who think this might make sense are the military experts and the grand strategists. Since the strategy is ultimately based on political reconciliation, I find it disturbing that none of the experts on the politics think that it could work.
