The West is spending a fortune in aid to Afghanistan. As the new head of Britain’s army recently pointed out, it is likely to have to go on supporting the country for decades. Yet the roads that are foreign development’s proudest boasts also serve to meet the insurgents’ and drug-dealers’ logistical needs.
That is inevitable: infrastructure serves the wicked as well as the righteous. But the West has not spent its money as well as it could have. By giving too many contracts to foreigners, it has created grudges instead of buying goodwill. To most Afghan eyes, watching heavily guarded foreign aid-workers glide by in their Landcruisers, it is obvious that much of the money is going straight back out of the country. To a degree, this is forgivable: in such a poor country it is difficult to build the capacity to manage huge volumes of aid, and channelling more of the cash through the government may mean that more of it gets stolen. But that is a risk that needs to be taken to build support for the West and the government.
Taking even the rosiest view, the war in Afghanistan is likely to get more expensive, and worse, before it gets better. The mini-surge this year to enable the election to take place in most of the country will probably be followed by another to try to contain the growing insurgency. For the moment, Mr Obama is better off than George Bush was when Iraq went bad, because he enjoys broad political and popular support for this commitment. But as casualties mount, political pressure in America to announce a timetable for military withdrawal will intensify. To resist it, Mr Obama will need more men, a better strategy and a great deal of luck.
