On January 5，2012 the United States announced a new military strategy report，publicly branded China and Iran as the main rivals and threats，but treated Russia politely. In the view of the U.S.，it has been unable to use threats to interfere with Russian foreign policy，though Obama knows that Russia under the leadership of Putin is the real strategic rival to the U.S.. Since the beginning of the new century，the U.S. military security strategy reports have always been very polite to Russia，while always taking China as the biggest threat. This is obviously an information psychological warfare against China. Before Iran’s nuclear issues are solved，U.S. will continue to issue threats against China through words or action intended to prevent China from aligning with Iran and Russia.
