The Bush administration briefly used "coalition of the willing" to refer to the countries who supported, militarily or politically, the 2003 invasion of Iraq and subsequent military presence in post-invasion Iraq. The original list released in March 2003 included 46 members.[2] In April 2003, the list was updated to include 49 countries, though it was reduced to 48 after Costa Rica objected[3] to its inclusion. Of the 48 countries on the list, three contributed troops to the invasion force (the United Kingdom, Australia and Poland).
