I think the point Tyto is making is that 2 elements in any war are useful and can cause major damage.
1) Underestimating the creativity of your enemy
2)Not preparing for the unexpected.
So, when I was in Iraq I drove through the desert and saw an abandoned air field with at least 30 jets from Sadaams old Air Force. Remember those guys? They were grounded the day the US came over the Kuwait border and were cowed rather than beaten. They fled and the planes were left to rot. The planes are still there. Did the US take imjportant stuff out of them to keep them from flying? I'm sure they did. The stuff is old technology. Not that hard to reassemble with money, time and intent. Especially when the US isnt there to babysit the air field anymore.
Ok so how does #1 or 2 fall in line with this?
1) Could an unknown crew of engineers walk into the airfiled, canibalize what they need, buy other stuff from a market 'not shy' to sell to them - and field the air crews with a professional group of people who have had American training -and- have since then become less than enamored with American politics? Well, I think it wouldnt be that difficult.
2) Could old airplanes shoot down American pilots of the Air Force? Pffft, a bullet is a bullet. And flying is flying--either skilled or not. So, could someone drop in on an airbase outside the US and take out an entire satelite of planes while they are grounded or even attempting to rise (like pearl harbor?) Why would anyone ever say that horrible phrase: never again? Could you get more cocky?
Possible meets probable when motivation, money, and training triangulate.
And that has nothing whatsoever to do with what you think they do to their goats.
