Matt Steinglass puts Afghanistan in perspective:
Afghanistan is a tiny, economically irrelevant country halfway around the world that has never had a stable central government. I don’t think the likelihood of our creating a stable, self-sufficient, non-Taliban government there is very good. And I don’t think the benefits of creating such a government, to the US, are really so high. And I think even the benefits of creating such a government for Afghans have been overstated. But let’s say we have a 75% chance of being able to do it. There is surely a maximum price tag at which we are willing to value that outcome. What is it?
One hopes that this question was at least asked under this administration. As opposed to the last one.
