Final answer:
During World War II, Einstein and other scientists had a plan to get the American government involved in the development of atomic bombs as a matter of survival.
Step-by-step explanation:
During World War II, alarmed scientists, including Albert Einstein, were concerned about the German potential to build powerful bombs of a new type. Leo Szilard, a physicist, took a draft of a letter to Einstein, who signed the final version. The letter was sent to President Franklin Roosevelt, urging him to make a serious effort at nuclear weapons as a matter of survival. This was their plan to get the American government involved in the development of atomic bombs.
