伊朗核问题的出现为美俄的战略争斗提供了新的内容。美俄围绕伊朗的弃核问题展开激烈的竞争和有限的合作。美俄双方在伊朗核问题上的表现和作用最终取决于美俄伊战略关系。美伊敌对和美俄的战略冲突是主导这个战略三角的基本要素。由于美国在核问题上需要俄罗斯的支持，而伊朗需要把俄罗斯作为屏障来防范美国的压力，从而使得俄罗斯在这个战略三角中处在两边谋利的地位。

The emergence of Iran’s nuclear issue has provided new contents for the strategic battle between the United States and Russia. The United States and Russia had fierce competition and limited cooperation over Iran’s nuclear issue. The performance and the role of the United States and Russia on Iran’s nuclear issue ultimately depend on the strategic relationship among the United States, Russia and Iraq. US-Iraq hostility and strategic conflict are basic dominant elements in this strategic triangle. Because the United States needs Russia's support on the nuclear issue and Iran needs Russia as a barrier to guard against pressure from the U.S., thus Russia is profit-making at both sides in this strategic triangle.
