As President, Truman ordered two atomic weapons, the culmination of the Manhattan Project, where Howard Stark and other scientific minds worked, to be dropped on the Japanese cities of Hiroshima and Nagasaki, bringing the war with Japan to a swift end.
After the war, Truman personally met Stark.
In 1946, when the SSR foiled Johann Fennhoff's plan to kill thousands of citizens of New York City, Truman sent Senator Walt Cooper to thank Jack Thompson for saving the city, unaware that it was Peggy Carter who prevented the tragedy.
