Politician: Some proponents of unilateral nuclear arms reduction argue that it would encourage other countries to reduce their own nuclear arsenals, eventually leading to an international agreement on nuclear arms reduction. Our acting on the basis of this argument would be dangerous, because the argument ignores the countries presently on the verge of civil wars. These countries, many of which have nuclear capability, cannot be relied upon to conform to any international military policy. Which one of the following most accurately expresses the conclusion of the politician's argument? ["It is risky for the politician's country to unilaterally reduce nuclear arms in hopes of achieving an international agreement on arms reduction.", 'Countries that are on the verge of civil wars are unlikely to agree to reduce either their nuclear arms or their conventional weapons.', 'It is unlikely that an international agreement on nuclear disarmament will ever be achieved.', "Unilateral nuclear arms reduction by the politician's country would encourage all countries to reduce their nuclear arsenals."]
