Unless negotiations begin soon, the cease-fire will be violated by one of the two sides to the dispute. Negotiations will be held only if other countries have pressured the two sides to negotiate; an agreement will emerge only if other countries continue such pressure throughout the negotiations. But no negotiations will be held until international troops enforcing the cease-fire have demonstrated their ability to counter any aggression from either side, thus suppressing a major incentive for the two sides to resume fighting. If the statements above are true, and if negotiations between the two sides do begin soon, at the time those negotiations begin each of the following must also be true EXCEPT: ['International troops enforcing the cease-fire have demonstrated that they can counter aggression from either of the two sides.', 'A major incentive for the two sides to resume hostilities has been suppressed.', 'The cease-fire has not been violated by either of the two sides.', "The negotiations' reaching an agreement depends in part on the actions of other countries."]
