Japanization of Okinawan Karate to Create Cultural Homogeneity within the Nation of Japan - September 12, 2022
Because Karate is such an essential pillar of an autonomous Okinawan subculture, its Japanization from Karate-Jutsu into Karate-Do became the mainland’s priority not just for militaristic purposes, but also to create cultural homogeneity across the nation.  
Itosu Anko Sensei’s Motivation to Teach Karate to Kids - April 4, 2022
Stressing Karate’s possible use for supporting Japan’s armed forces was Itosu Sensei’s pragmatic strategy to secure sufficient funds for his educational campaign by tapping into Japan’s funds for its militarization―whereas the final and underlying goal of this educational campaign was not to create the raw material for the nation’s military forces, but something different, something nobler.
Peaceful Minds Through the Study of Lethal Okinawan Karate? - January 17, 2022
Through building up physical and mental strength, inappropriate overcompensating and aggressive tendencies lessen and eventually even vanish, since traditional karate training creates new self-definitions of capability and new self-perceptions of being able to successfully defend oneself and others. Unavoidably, self-confidence and courage eventually will improve and reduce feelings of inferiority.

Applying a comparable argument, an existing Okinawan martial art with its clear intention and purpose of self-protection integrated foreign (here: “Chinese”) knowledge and skills as a useful improvement into its existing system, into its existing idea, its existing concept and intellectual framework.”
Defending Against Multiple Assailants Part 2 - July 25, 2016
The axiom that street violence is volatile and unpredictable could not hold truer than when facing multiple assailants.  Facing multiple assailants, let alone multiple armed assailants, is an extremely dangerous proposition.  Try to recognize the situation as soon as possible such as if two people are walking towards you and they suddenly fan out to your left and right.  Running and escaping is your best solution.
Defending Against Multiple Assailants—Part 1 - July 18, 2016
Street violence is volatile and unpredictable.  An attacker will seek every advantage including ambushing you in concert with multiple confederates.  You may well find yourself in a "negative five" position or initially unprepared for the fight of your life.  Krav maga (Hebrew for "contact combat") developed for the Israel Defense Forces will provide you with the instinctive tools and ability to fight for your life and win.
Optimizing Force Using Krav Maga - April 12, 2016
A combative strike will have optimum force if you accelerate your strike in combination with correct body mechanics. Principally, this involves a total body weight shift through the target. Physics teaches that acceleration times mass equals force. Your strike will generate more force if you accelerate your speed as you extend your arm and put all of your body weight (mass) behind your strike. This requires proper body positioning and technique.
The Krav Maga Advantage - March 29, 2016
The key is your mind-set: to neutralize an opponent quickly and decisively. In fighting sports, the following tactics are generally banned: eye gouges, throat strikes, head butting, biting, hair pulling, clawing, pinching or twisting of the flesh, striking the spine and the back of the head, striking with the tip of the elbow, small joint manipulation, kidney and liver strikes, clavicle strikes, kneeing or kicking the head of an opponent on the ground, and slamming an opponent to the ground on his head. These are exactly the combined core tactics krav maga emphasizes.

Footwork and body positioning combined with timing, whether standing or prone, allow you to simultaneously defend and attack, leading to seamless combative transitions essential to retzev or "continuous combat motion."
Krav Maga's Training Philosophy - January 25, 2016
Krav maga is designed around a few core tactics to counter a myriad of attacks. Defenders get tools for their toolboxes along with a general blueprint for how to use them.

While there are no set solutions for ending an armed confrontation, there are preferred methods using violence of action combined with retzev, or "continuous combat motion."
The Players in Self-Defense - February 2, 2015
No matter what levels of force you need, the players stay the same. It is critical to be able to read the players. The threat dictates the situation. You must understand the problem before you can choose a solution. A charm predator is one thing. A drunk wanting to show off for a girl is an entirely different problem. You must learn to read threats and threat dynamics.

According to the National Institute for Occupational Safety and Health, 18,000 people a week are victimized by some sort of workplace violence in the United States.

How do you know when it is legal to get physical with an adversary? Learn the I.M.O.P. (Intent, Means, Opportunity, and Preclusion) principle.

Account for Adrenaline - September 1, 2014
