The United States has ABOUT 300 million people. (Who knows how many illegals we have.)
The Aussies have about 20 million.
So for the Aussies to equal the American participation on Iraq by quota share, they would only have to send an additional 8,000 troops, not the 20,000 Husseain-Osama-Obama claims.
If a REPUBLICAN made that gross a mathematical error, it would be headline news for a week.
