Which would utterly destroy the US economy and do more damage than any drone attack.

Plus imagine if those attackers realize they can ship those containers from Mexico or Canada.

Pretty sure it would destroy whoever is on the other side of those shipping containers too though

> whoever is on the other side of those shipping containers

Could take a while to figure that out. It took days/weeks to figure out the 9/11 attacks with some certainty.

I'm not sure what that does for whoever initiates the attack. They still eventually get found out and unless they've managed to conquer the US, everyone is now bankrupt.

> everyone is now bankrupt

A good reason enough for a lot of people, no?

How far off are palm sized drones that have light weight solar panels on them that can flit about here and there and sit and wait and recharge in unobtrusive locations until they make their way to their target?
