1) That may be your opinion but - TKD is what they teach the soldiers in the Korean armed forces (soldiers fight wars)
Yes, soldiers fight wars. And when TKD was developed, soldiers fought wars
with guns. Taekwondo was not ever a military art. Just because soldiers train in it does not mean that they are doing so with the intent of using it in combat. American soldiers train in BJJ, primarily to keep their competitive edge up. Nobody expects them to go out and grapple on the battlefield.
I am very familiar with the history of taekwondo. Do not delude yourself into believing that it is anything resembling a war art. It is not. It is a civilian fighting system with roots in Shotokan, which was gendai budo employed in Japanese schools. It never was a war art. Opinion never was a part of it.
... and Judo is what they teach the police force in Japan - no guns there. Judo came out of JuJutsu, which was used in war... by Ninja and Samurai, alike.
Japanese police also practice kendo. However, police are not at war. They are trying to restrain people.
As far as jujustsu, unarmed combat was a very last resort. The primary implements of war, and the primary war arts, all involved weapons. By the time Kano invented judo, Japan had already transitioned to a modern military. Also, saying "jujutsu was used in war" is misleading. Not all jujutsu ryu were used in war. I'm not familiar with what ryu Kano was trained in, but regardless, the judo that he invented was not a military art.
2) Adding water to lemons, makes lemon-ade. Not what I'm talking about. Perhaps I made the wrong analogy. TKD and JUDO have been robbed of very many good techniques that are legit and realistic, and function well in competition as well as in a real street fight... some of which are still being used in other styles, like Wrestling, Sambo and BJJ.
Adding water to soup or wine is watering it down. Not familiar with sambo (not the MA anyway), but wrestling and BJJ are not war arts. Never have been.
3) It's called San-Chou. Cung Le is the man in this particular sport-M/A style. He beat Frank Shamrock pretty bad in their match a few years ago.
I am familiar with Cung Le. Great fighter. I think he broke Shamrock's arm if I recall.
By modern standards, most of the arts discussed on this board are not martial. Many never were. The guy in the Air Force learning to fly a plane and bomb the crap out of a city is learning a martial art. The guy in the dojo learning judo is learning a fight sport. The guy in the dojo learning kenjutsu is learning to keep ancient traditions alive and to preserve them for future generations. The judoka may be able twist you into a pretzel and break you and the kenshi may be able to cut you to ribbons, but neither is learning a skill that has application in war.
