NATO Facts

Although no members have criticized others by name, eight of the 26 countries are providing more than three-fourths of the alliance's 20,000 troops now in Afghanistan. Many members are providing fewer than 200 troops. Poland, for example, has contributed 10 soldiers to the mission, according to NATO officials, although it pledged last week to send about 1,000 more.

The United States has 21,000 soldiers in Afghanistan, more than any other NATO member, but only 1,300 are part of the alliance's operation; the remainder are under exclusive U.S. command. Britain is currently the largest contributor to NATO's force in Afghanistan, with 5,000 troops.
