One problem for achieving world peace, according to experts, is the reduction in the proliferation of weapons.

Answer - True

According to experts, one major challenge in achieving world peace is how to control and probably abolish the proliferation of weapons, particularly weapons of mass destruction (nuclear weapons). The Non-Proliferation Treaty (NPT) functions as the legal international instrument that sets the ethical rules to bind its parties to reduce their nuclear weaponry and to encourage the peaceful uses of nuclear power.
