Treaty Focus for 1968

The question asks to identify a specific treaty established in 1968. This treaty was imposed by the world's five nuclear weapon states, which are also the five permanent members of the UN Security Council (P5 nations: China, France, Russia, UK, US), upon the rest of the global community.

Analyzing the Treaty Options

Let's examine the provided options in the context of the 1968 timeline and the entities involved:

• Comprehensive Test Ban Treaty (CTBT): This treaty prohibits all nuclear explosions for weapons purposes. However, it was not opened for signature until 1996, making it chronologically incorrect.
• Non Aligned Treaty: This likely refers to the principles or agreements associated with the Non-Aligned Movement (NAM). NAM was founded in 1961 and focuses on neutrality in Cold War politics, not a specific treaty imposed by nuclear powers in 1968.
• North Atlantic Treaty Organization (NATO): NATO is a military alliance established in 1949. Its primary focus is collective defence among member states and does not align with the description of a 1968 treaty imposed by nuclear powers on global non-nuclear states.
• Non-Proliferation Treaty (NPT): Signed in 1968 and effective in 1970, the NPT aims to prevent the spread of nuclear weapons and weapons technology, promote peaceful nuclear energy, and further the goal of nuclear disarmament. The treaty was negotiated and established by the five nuclear-weapon states (who are also the P5 members of the UN Security Council) and aligns perfectly with the question's description.

Conclusion on the Treaty

Based on the timeline (1968) and the parties involved (five nuclear powers/P5 nations imposing it on others), the Non-Proliferation Treaty is the correct identification.
