but have you noticed that the personal protection organizations for both the US President and Hitler have/had the same initials?

Secret Service and Schutzstaffel are/were both abbreviated SS (although the Germans used the runic version of the letters, it was still pronounced SS).

I can also point out some changes made to the US Army uniform which make it strikingly similar to the uniform worn by the German Army of the past two world wars.
