U.S. soldiers sent to aid the White Russians against the Bolsheviks in W W I. U.S. POWS held by Nazi Germany in WW II, at least 25,000 of them, taken by the Soviets and held in Gulags worked to death, whose existence was denied to prevent their publicly being used to negotiate U.S. concessions of money and aid to Stalinist Russia.
Likewise U.S. POWs in Korea. One report 8,000 known POWs. Another 900-1,200 known POWs that Eisenhower himself was informed of.
Likewise U.S. POWs in Vietnam.
Tens of thousands of U.S. POWs that the U.S. government knew about, denied their existence, and let them spend their entire lives in captivity.
A very enlightening and well produced documentary on the subject.
