"Executive Order 12464, dated 23 February 1984, authorized award of the Purple Heart as a result of terrorist attacks or while serving as part of a peacekeeping force subsequent to 28 March 1973."
This looks pretty clearcut to me.
These kids died as a direct result of their service to this nation during a war by a direct attack from the enemy.
All that is needed is for this administration to declare that this was a terrorist attack.
That won't happen.
Neither will the bill ever reach the CIC's desk.
