In World War I we were pulled in due to the sinking of the Lusitania, which carried American passengers but also arms and ammunition. Officially, it was carrying 750+ tons of small arms ammunition as well as ~1200 artillery shells. If we and Britain (it was a British ship but was leaving from New York and headed to Liverpool) had simply segregated passenger ships from government arms transportation, that incident wouldn't have happened and America wouldn't need to get involved in WWI.
In WWII we cut off interaction with Japan at various stages due to their expansionism and helped the Chinese and British territories with monetary loans and weapons. This also included cutting off scrap metal, of which we were responsible for ~75% traded to Japan, and after Tojo rejected pulling out of China we also embargoed our oil shipments to them which were similarly majority in Japan's income of that resource. This pushed Japan to move to cut off peace talks and pull Pearl Harbor.
In short if the US didn't feel some weird need to help the retarded Anglos we would have literally no link to either world war and I think we should not have helped the soon-to-be former empire with their own retarded messes, thanks for coming to my TED Talk.
