That is the best argument
I tend to agree with you. But he wasn't (isn't) alone in his hatred for all things American.
Don't underestimate their patience.They spent years planning 9/11.
I too believe Osama is dead & has been for some time. I have read that suitcase nukes, if there is such a thing, have an expiration date, kind of like milk. You can't just put one in the closet like luggage for several years & then expect it to work.
An enemy with navys, and armies fights in very different ways. They cannot simple plan an attack in two weeks and send in their airforce. 911 was years in planning and they pulled it off almost perfectly. If not tactic nukes, it'll be something most haven't thought of.
It's enough to make one's hair stand up, as I read about trucks packed with hundreds of illegal aliens, that cross our borders routinely, most never being detected.
Think about how easy it would be, to enter America from the corrupt country of Mexico, where law enforcement can be bribed with protitutes or small amounts of cash. Trucks with unknown loads are entering as we speak. Think about that.
