Don't forget also the role played by Gen. Choi. During the Korean War and after, he made some very aggressive moves against the other kwan founders, using his clout in the ROK military (and later in the Park military dictatorship after the 1961 coup, which Choi had supported enthusiastically). In work by Dakin Burdick in JAMA (1997) and in our own Robert McLain's interview with Gm. Kim Pyung-Soo (available in our own MT Martial Arts magazine), there is documentation of at least the following actions:
(i) during the war, Gen. Choi offered other Kwan founders, senior instructors and senior students the following choice: a soft assignment well behind the front lines, if they switched to his organization, or an assignment to an active sector at the (horrifically dangerous) front, if they declined;
(ii) retesting of all black belts by Choi's Korean Taesudo Association (with the strong backing of the Park regime) to establish `national standards';
(iii) an attempt by the KTA to have the Moo Duk Kwan's charter from the Korean Ministry of Education revokedĀa case that went all the way to the Supreme Court of Korea, which ruled in Gm. Hwang Kee's favor.
In addition, according to a letter from Robert Shipley to Black Belt magazine in 1975, Hwang Kee's house was `partially burned by "persons unknown" ' in 1973, and Gm. Kee left for the U.S. the following year.
I don't think it's unfair to say that it was largely a result of Gen. Choi's attempt to impose a monopoly on control of the KMA, using his enormous influence and authority, that resulted in the imposed `unity' that led to the disappearance of effective Kwan identity in most cases, and the separation of MDW (and hence TSD) from the KTA and later government-based central Korean MA organizations.
But I also believe that the split was further ramped up by the fact that HK viewed the tangsoodo/kongsudo practices in the original and later kwans as a set of fighting skills, whereas the WTF, in the aftermath of Choi's fall, saw it as a way to enhance Korea's status not in terms of military survivalĀthe version of TKD that Gen. Choi promoted was, after all, a very direct, linear, brutally effective combat skill set designed to incapacitate and kill enemy soldiers in H2H fighting as quickly as possibleĀbut in international sports competition, in the aftermath of the military demand on the ROK armed forces in Korea and later in Vietnam. TKD, in the hands of the WTF, aimed at Olympic glory and got it; my impression is, TSD continued (and continues) Gm. HK's focus on the Okinawan/Japanese fighting skills that the kwan founders learned, and returned to teach, before the war. (There are a lot of TKD practitioners out there, many on this board I suspect, whose view of their art is far closer to the main TSD line than the WTF/KKW line, but that's a differen story... )
