Answer:
The 2003 invasion and occupation of Iraq is widely considered to have been one of the biggest military blunders in U.S. history. Its failure to achieve intended war aims is reflected in the fact that 11 years after the operation began, Washington today is debating what steps should be taken to slow the advance of Islamic militants toward Baghdad. Rather than establishing a stable, self-sustaining democracy, the U.S. occupation unleashed forces which may now lead to the country's breakup -- not to mention millions of casualties.
