The "He's running away!" line strikes me as wishful thinking mixed with a sense of patriotism which was, for obvious reasons, not very high in Japan at the time.
Godzilla himself was already in the water by the time the airforce arrived, so the situation seems pretty obvious.
That being said if there's some sort of comparison between 2014 and 1954 going on here I don't think either "ran" from the military. I just think Godzilla was slightly annoyed by them in 1954 and he was rather one track minded in 2014.
But Gorilla,
You really need to stop taking these opinions of G'14 so personally that you slueth for flaws in other films to make it seem better. I think the reality of where the 2014 film (and monster) sits within the grand scheme of the series is finally starting to sink in with fans. The bias hype has effectively died. It happens with EVERY Godzilla movie and I've now watched seven "fall from grace" after the honeymoon period-- Roughly 5 to 6 months after the movie is released. Being your favorite Godzilla movie and incarnation of the monster is fine, but loving those aspects also demands understanding its flaws. That way you understand why they don't connect with some people.
