Fact is, terrorist activities are impossible to defend against. They need innocent people to be victims. Otherwise, it's not terrorism. Actions against innocents will cause nations to do exactly what the USA has done. Maybe that was the goal.

Attacking a military installation is not an act of terrorism. The purpose of terrorism is to terrorize civilian populations. We have always held it to be 'understood' that civilians are sacrosanct in times of war. Not so, but we've generally thought it to be so. Warfare has changed, because it is no longer possible for the weak to fight 'fairly'. Therefore, the strategy changes and the tactics change as a result. I do not like attacks on innocents, and that is why I could never be a terrorist. But, it seems that people can put ideology before humanity. Welcome to the brave new world.
