ILYA SOMIN: Just Say No To Terrorism. “Giving in to the terrorists incentivizes further terrorism, while refusing to do so reduces the risk of future violence. This principle applies to terrorism more broadly: An excellent way to reduce the risk of attacks is to refuse to give in to the terrorists’ demands. Over time, a government that develops a reputation for saying no to terrorists is likely to suffer fewer attacks in the first place. . . . Saying no has many advantages over alternative antiterrorism policies. Unlike defensive security measures, it doesn’t require much in the way of extra government spending or violations of civil liberties. It is also less costly than offensive military action against the terrorists and creates fewer collateral risks.”

This does not seem to be our current approach.
