It is very likely: the atomic bomb was initially built to defeat Nazi Germany, and the Manhattan program was started before Pearl Harbour. When you read The Atomic Bomb book, many scientists who worked on the bomb justified their effort by defeating the Nazis, and many had to escape from Europe.

Once it became clear Nazi were about to be defeated, there were discussions from the scientists about sharing the knowledge w/ all countries. But at that point, the scientists had long lost control over the project.
