I can understand why you feel that way, but I look at it differently. I see it as the jihadis being so poorly trained that they don't know to use the right arms...thus wasting the arms that they do possess.
The SA-7 through SA-18 manpads are wholly unsuitable for bringing down big birds. There was one commercial jet hit by one of those weapons back in 2003 or 2004 and the pilot landed with no casualties...plane was repaired and flew again. 5 pounds or less of high-ex isn't going to bring down very many 50,000 pound aircraft (much less larger birds).
The soviets only built them as nuissance weapons...just to give our jet pilots a 2nd thought about flying low.
But by firing at a jet, the jihadists wasted a missile that could have caused U.S. casualties in a helicopter...so I see this as a good thing for us.
Let them waste their ammo; it's good that they don't know any better.
Just a quick note. My brother is alert, awake and breathing (mostly) on his own. Still in the woods, but Drs very pleased with his progress. He's showing some of his humor which is also good. All your prayers have been very appreciated.
"...it's good that they don't know any better."
OPINION: Ditto and Amen to that.
