Why place the Great within quotation marks? The proper name of the place is Great Britain... the Great doesn't require quotes any more or less than the Britain does.

1) the question is quite difficult to answer, because the concept of allies could vary with time and particular situation. Some allies would engage themselves also much more than others at the side of the US, other could have different goals or diffrent ideas about how to achieve them. 2) Here some information about the US allies in Irak: "The Multi-National Force - Iraq (MNF-I), is a military command, led by the United States, that is fighting the Iraq War against Iraqi insurgents. Multi-National Force - Iraq replaced the previous force, Combined Joint Task Force 7, on May 15, 2004. The media in the U.S. has been known to use the term U.S.-led coalition to describe this force, as around 93% of the troops are from the United States. The majority of nations that deployed troops either confined their men to their bases due to widespread violence, or issued specific orders to avoid hostile engagement (especially true of the Spanish commanded Plus Ultra Brigade). Also in Iraq, but not part of MNF-I, are the United Nations Assistance Mission in Iraq, which is doing humanitarian work, but has a number of guards and military observers, and the NATO Training Mission - Iraq, training the Iraqi army and police force." "Four countries participated with troops during the initial invasion (termed the Major Combat Operations phase), which lasted from March 19 to May 1. These were the United States (250,000), United Kingdom (45,000), Australia (2,000), and Poland (194)."

Well, there's also the United Kingdom and England.

These are the NATO countries they are all allies: Belgium, Bulgaria, Canada, Czech Rep.,Denmark, Estonia,France, Germany, Greece, Hungary, Iceland, Italy,Latvia, Lithuania, Luxembourg, Netherlands, Norway,Poland, Portugal, Romania, Slovakia, Slovenia, Spain,Turkey, United Kingdom and United States. The forces they deployed for the past two wars are as "Iwnit" has said in his accurate answer. These countries provide the armed forces they are able to, as many of these countries are not large nor rich. The Latin American countries are always allies of the United States. The difference is that Latin American countries provide their troops through the United Nations either for combat or as a Peace keeping Force due to constitutional issues. During the past two wars the United Nations did not support the situation and a UN Resolution was not issued for Iraq and Afghanistan, most of the stronger EU countries had to withdraw their troops as they had tremendous problems with their populations who did not agree with said circumstances. The Latin American countries are still there but as Peace Keepers and send by the United Nations. Regards.

There is another one that has not been listed, Japan. Because of a clause in their constitution, they may not deploy troops to other nations, but they are still a pretty strong ally of ours.
