I bet you if you could pole people that lived in the USA back in 1940 and what they thought about Japan invading Pearl Harbor, they would have said that was dumb also. The movie was not about the method of attack, it was about incidents leading up to the attack. We are vulnerable in many ways, we have to identify those ways, and stop it. Like we did in NJ earlier this week.
Can’t say I didn’t disagree with the message. Kinda like an Ayn Rand novel, GREAT ideas, LOUSY writing.
