I don't know much about war but since Russians love to compare themselves and their strength to a country like the USA while pretending no one's got shit on 'em here's the timeframe of when the USA invaded Iraq.
2003 invasion of Iraq: 20 March 2003 – 1 May 2003
Length: 1 month, 1 week and 4 days.
Also:
"On April 9, 2003, just three weeks into the invasion of Iraq, U.S. forces pull down a bronze statue of Saddam Hussein in Baghdad's Firdos Square, symbolizing the end of the Iraqi president's long, often brutal reign, and a major early victory for the United States."
