Al-Qaida terrorists, or terrorist members of any global network acting against the US, should be given a military trial, as provided already by US law.

For them, an honorable death is important. Military tribunals work for American soldiers, so why not for terrorists? It is foolish to avoid it and delays the end by many years.
