Our country, the United States of America, may be the worlds largest economy and the worlds only superpower, but we stretch ourselves dangerously thin by taking on commitments like Iraq with only a motley band of allies to share the burden.

We developed during the 1990s a series of budget process rules that helped us bring to heel these deficits, diminishing every year and moving the budget so into surplus.

This war so far has cost us $125 billion and counting, because largely we decided to do it on our own, with only the United Kingdom as a paying, fully participating partner.

Just a few short years ago in the year 2000, the last full fiscal year of the Clinton administration, this country was running a surplus of $236 billion.

Three big assumptions proved wrong: one, that the Iraqi people would welcome us as liberators; two, that oil would soon pay for Iraqi's rebuilding; and, three, that we have plenty of troops, weapons, and equipment for the postwar situation.

Democrats and Republicans alike support our military personnel.

As costs mount, in lives and dollars, it is natural to second guess, but one lesson I hope we have learned is that the U.S. cannot go it alone in a policy that leaves American troops taking all the risk and American taxpayers paying all of the costs.
