Rebuilding Haiti means not only recovering from the earthquake but also building infrastructure for the future: It’s when we start talking about longer-term solutions that the discussion gets clouded by preconceptions, dogma and real-world practicalities. Sixty years after the Marshall Plan proved that foreign assistance can work, some of the time, we still find our best-meant schemes mired by bureaucratic inefficiency, corruption, and unintended consequences. Nor does any political side have a perfect recipe. If the American left has often shown itself to be treacly and naive, the right is already back to its old, cynical sneer, deriding “the failed and discredited utopian fantasy of so-called Nation Building” — an actual neoconservative mantra, up till the very month that they plunged the U.S. into the most costly, inefficient, corruption-ridden and ill-conceived nation-building exercise ever undertaken. Now, the mantra that went dormant for a while is back.
