Refusing to negotiate with terrorists isn’t a strategy designed to produce the best outcome in isolation. It’s to avoid providing incentives for more terrorism, despite the consequences viewed in isolation.

So “outcomes are worse if you don’t” is not relevant. Several times as many terrorism incidents with better outcomes on average is not what most people would consider effective anti-terrorism.

The discussion went through ransoms, hostages and terrorism. It's inappropriate to reply to all situations with "we don't negotiate with terrorists".

Refusing to negotiate with terrorists is not a real strategy practiced by anyone. It’s just tough PR talk with zero basis on reality.
