I think that in order to be considered an act of war, the group must be part of a military group or country with uniforms. This is per the Geneva Convention. I don't remember all the other requirements, but I do know that if the group don't wear uniforms then the act is not considered war.
This separates soldiers in uniform from a civilians. Then a terrorist is someone which doesn't wear uniform by default.
They also don't get the same rights as POW's and the thus the Cuban resort.
We have the 9/11 Memorial and the Pearl Harbor War Memorial.

Congratulations you made the president look bad for a minute at the expense of a fallen soldiers family and loved ones. Good job you real Americans.
