Heartily agree! We've heard for MONTHS how we are "all going to die soon". Yet, time ticks on, and we are all still here - and I wager will be 12 months as well as 12 years from now.
I am not discounting the overall threat, and think that AQ probably DOES have WMD. But I think we've foiled many potential attacks and will continue to do so.
I also think there's a whole lot of crackpots just posting to 'net BBs as they don't have any other way to hit us. That, and people who outright hate the US and just want to scare us into submission (hint: it's not working). Finally, I think there are (sadly) also people who run "analysis" websites who have other motivations for helping to stir the pot up a bit.
All of this contributes to a high noise/signal ratio, IMHO, although we certainly have to take a look at everything and consider it fully.
