It would be less expensive and more fruitful for America to tackle the Israeli-Palestinian conflict, return to a multilateral approach, and respect the moral principles that it recommends to others.

如果美国能够处理好巴以冲突、重新采用多边方式、并尊重它向其他国家推荐的道德准则，那么它在处理当今危机的时候也许能够少付出一些代价，多取得一些成果。

可能不会，但是，如果美元从霸主位置跌落，美国人肯定会发现其全球霸权将会大为费钱。
