Who said anything about "world class fighters"?I was going to mention that. You ever fought an IDF guy? I haven't so where was it decided IDF guys are world class fighters?
As mentioned earlier, the effectiveness of styles of training and the effectiveness of styles of MA are two different questions. The questions was whether KM was effective in self defense, not whether my KM training is effective for self defense (which it can't be, because I don't train in KM).And that is before we even address whether or not you are being trained by the guy who trains the IDF. Which of course you are not.
Because it has been and is used in self defense situations. I'm assuming that the IDF has actually used some of their training in real life. If they have not used their training, and they just continue to train in Krav Maga for the sake of training in Krav Maga, then I'd have to reassess my assumptions.So ignoring then mma as a testing ground why is krav effective?
