"Let`s never forget that to remain free we must always be strong. "
- Glenn Ford
In The Fastest Gun Alive Ford plays a reluctant gunfighter (a theme that occurs in several of Ford's Western roles) who is reluctantly forced into taking up arms against the badguys. We may well be seeing Ford's personal philosophy at play here, whereby he expresses the need for a vigilant defence in our troubled world.
Wikipedia: Ford's World War II decorations are as follows: American Campaign Medal, Asiatic-Pacific Campaign Medal, World War II Victory Medal, Rifle Marksman Badge, and the US Marine Corps Reserve Medal. He retired from the Naval Reserve in the 1970s at the rank of captain.
