二十年后，美国正式从伊拉克撤军，留下一个饱受摧残、夹在美国与伊朗之间的国家。
After two decades, the U.S. formally withdrew from Iraq, leaving behind a battered nation trapped between the U.S. and Iran.
据最保守的统计，美国的入侵及随后的占领导致近4500名美军丧生，超过11.5万名伊拉克人死亡。
The U.S. invasion and subsequent occupation cost nearly 4,500 U.S. lives and killed more than 115,000 Iraqis, according to the most modest counts.
