bg, read the posts and you’ll see why I mention China. Just an example that we are not the only powerful military in the world, and coalition support is a good thing to have.
Those “coalition” countries are insignificant to the Iraq war effort. They account for less than 10% of the troops and less than 10% of the casualties. In case you flunked math, that means the USA has the burden of over 90% of troops and casualties.
Not sure why you are counting Iraq casualties as coalition, since Iraq is the country we invaded and are occupying.
