 The second variant of coercive diplomacy, 'Tacit ultimatum', is similar to 'ultimatum' except that it doesn't set forth an explicit time limit.The third variant of coercive diplomacy, the 'Try-and-See', addresses strictly the first component of the 'ultimatum' variant, "a demand on the opponent".There is no time limit set, no sense of urgency conveyed, instead the coercer makes a single threat or takes a single action "to persuade the opponent before threatening or taking another step".
