Input: Read this: Von Neumann is credited with the equilibrium strategy of mutual assured destruction, providing the deliberately humorous acronym, MAD. (Other humorous acronyms coined by von Neumann include his computer, the Mathematical Analyzer, Numerical Integrator, and Computer—or MANIAC). He also "moved heaven and earth" to bring MAD about. His goal was to quickly develop ICBMs and the compact hydrogen bombs that they could deliver to the USSR, and he knew the Soviets were doing similar work because the CIA interviewed German rocket scientists who were allowed to return to Germany, and von Neumann had planted a dozen technical people in the CIA. The Russians believed that bombers would soon be vulnerable, and they shared von Neumann's view that an H-bomb in an ICBM was the ne plus ultra of weapons, and they believed that whoever had superiority in these weapons would take over the world, without necessarily using them. He was afraid of a "missile gap" and took several more steps to achieve his goal of keeping up with the Soviets:
Question: What was the goal of MAD?

Output: quickly develop ICBMs and the compact hydrogen bombs that they could deliver to the USSR


Input: Read this: The Chronicle reports that Askold and Dir continued to Constantinople with a navy to attack the city in 863–66, catching the Byzantines by surprise and ravaging the surrounding area, though other accounts date the attack in 860. Patriarch Photius vividly describes the "universal" devastation of the suburbs and nearby islands, and another account further details the destruction and slaughter of the invasion. The Rus' turned back before attacking the city itself, due either to a storm dispersing their boats, the return of the Emperor, or in a later account, due to a miracle after a ceremonial appeal by the Patriarch and the Emperor to the Virgin. The attack was the first encounter between the Rus' and Byzantines and led the Patriarch to send missionaries north to engage and attempt to convert the Rus' and the Slavs.
Question: What years did Askold and Dir make peace with Kiev?

Output: unanswerable
