The 反アメリカ (Anti-USA) militant group was a military group that consisted of soldiers who used to fight in WW2. They acted from 1946 till roughly around 1970-1972. These soldiers were against the American occupation and did as many assassinations and terrorist actions as they could, which was very little. Their acts were small and they did not act as a big group to the point that some people never considered the 反アメリカ group as an actual militant group and ruled them as either part of other terrorist groups like the Red Army or even rouge citizens that were against the American occupation. Whether this group existed or not the damage they did to Americans and Japanese alike has happened and has affected Japan even if it is small. But one question remains, were they right? I will end it here and allow you to form your own opinion on this matter.
