I'm glad you're not in charge of US policy. Underestimating an enemy is a great way to lose a war.
The jihadists were smart enough to find the gaps in our pre-9/11 airline security, and exploit them masterfully to murder 3000 Americans. Credit where credit is due: 9/11 was murderous, evil, a crime against the laws of war, cowardly as an attack on defenseless civilians, but it was also brilliant in its tactical conception and execution.
And it doesn't take a genius, or a state secruity apparatus to figure out how to make chlorine gas and bottle it. Anyone with access to a compressor of the sort used to make pressurized gas cylinders and household chemicals can do it.
All the other FReepers who made chlorine gas using household chemicals when they were kids chime in now.
It's the strategy that they don't have the smarts to figure out for themselves. And they also don't have the anti-helicopter missiles without help.
