Perhaps he meant we have not faced double-digit SAM's operated by highly-qualified (proficient) crews who were willing to counter our SEAD capabilities. That does not mean they don't exist (they do), just that we have not fought them.
That statement I could more easily agree with
Radmanly, there are very capable SAM's out there - luckily, even our greatest potential enemies try to limit those best systems being exported (not because we may end up facing them, but because they may). SAM's are complex and require good equipment, good tactics, and good operators - our recent adversaries didn't really have all 3 going for them across the board. They also work best as a system when tied into a larger air defense system - like anything else, keeping it all running (the whole IADS) at 100% is difficult in real life.
Integrated is the key here. We have done a real good job of distruption and preventing integration.
With that being said, most nations in the Middle East realized that SAM's still gave them the best bang for the buck. With our long-established air superiority, buying expensive aircraft just so they could get shot down would not be cost-effective.
Double digit MANPADS don't take a lot of training to employ; luckily we haven't come up against many.
