It wasn&#x27;t just the Nazis. Amphetamines were used by many different militaries to varying effects, including the US. Hitler&#x27;s drug use is also well documented. (As is JFK&#x27;s.)<p>It&#x27;s really not hard to believe. The current form of drug treaties and opinions is a distinctly post WWII phenomenon.<p>I believe the US military still offers drugs to its soldiers, but they are very strictly regulated and presumably are more rationally provisioned. War can be very mentally and physically stressful, and drugs tend to be the best short term option to ameliorate this stress and keep the machine running.<p>Nothing like meth or speed, though. Terrible for soldiers. I believe there is a high association between meth use and vulnerability to mental trauma.
