During the Cold War, which factor was not a reason for restraint in attacking satellites?

• A. The close relationship of space and nuclear missions made each party careful not to do anything that might be destabilizing.
• B. The 1967 Outer Space Treaty and subsequent agreements made space a legal sanctuary from war.
• C. Each side wanted to preserve freedom of space in order to conduct satellite reconnaissance.
• D. Nuclear attacks in space would have been highly provocative, and technology for conducting conventional attacks in space was not well developed.

Answer: (B)

The restraint you’re looking for comes from the practical risks and strategic norms of the era, not from a legal shield in space. Attacking satellites was seen as dangerous because it could trigger rapid escalation, draw in broader military responses, and undermine critical military capabilities tied to space assets. The close linkage between space operations and nuclear mission planning made actions in one domain potentially destabilizing for the other. Both sides valued space reconnaissance and communications, so damaging satellites would impair vital capabilities and invite reciprocal moves. And by the time, the technology to conduct reliable conventional anti-satellite attacks was not well developed, which further discouraged reckless attacks.

The statement about the 1967 Outer Space Treaty and similar agreements making space a legal sanctuary from war does not really provide a strong, concrete restraint. The treaty prohibits weapons of mass destruction in space and promotes peaceful use, but it does not declare space a guaranteed sanctuary or ban all forms of warfare in space. It sets broad norms rather than a hard shield, so it didn’t serve as a direct, binding reason that prevented attacks on satellites.
