Some suggest that the US constitution provided fewer constraints on the president in the conduct of foreign policy, because the requisite checks and balances were to be provided by the powers of the time - Britain and France. Today, with the US as the only superpower, it is even more important for countries to stand up and express their views - and to stick by them even when pressured.
在美国可能继续单边主义的情况下，其他国家的立场也许会对改变这一状况起到一定作用。一些人提出，美国宪法在总统实行外交政策方面限制较少，因为当今世界另外两大强国――英国和法国还会对其进行必要的制衡。美国以独一无二的超级强权形象出现在今天的国际舞台，其他国家能够在这种情况下站起来、说出自己的观点，并且在面对压力的情况下仍然坚持下去就显得尤为重要了。
