Which British Prime Minister authorized the UK's creation of its own hydrogen weapons?

• A. Harold Wilson
• B. Anthony Eden
• C. Harold Macmillan
• D. Winston Churchill

Answer: (D)

The question tests understanding of who gave the green light for Britain to pursue its own thermonuclear (hydrogen) weapons as part of maintaining an independent nuclear deterrent during the Cold War. The decision to move ahead with hydrogen weapons was made under Winston Churchill in the mid-1950s, as Britain sought to ensure it could deter would-be aggressors with its own advanced arsenal. This authorization set Britain on the path to develop thermonuclear capability, even though the actual hydrogen tests occurred later under his successors (the first tests were in the late 1950s). The move reflected a policy aim: to preserve national security and international standing by not relying solely on others for a nuclear shield.
