The War in Iraq cost nearly $2 trillion, roughly $8,000 per U.S. taxpayer, representing 9 percent of the national debt. The current cost to the federal government for conflict zone operations in Iraq is an estimated $1.922 billion ... according to an analysis and a January report from The Cost of Wars project. Without a war tax and few war bonds, direct war spending on post-9/11 wars by the Pentagon resulted in interest payments of about $444 billion, the report estimated. The author warns even if the fighting stopped today, and the Trump Administration pulled out of all ongoing fights in the "Global War on Terror," those cumulative interest payments would continue to rise. If all war spending stopped today the existing war debt would "rise ... to $6.5 trillion by 2050," according to the report's estimates. Over the last 18 years of engagements in South Asia and the Middle East, the American "government has financed this war by borrowing funds," writes Heidi Peltier, the author of the report. War is more costly than just boots on the ground and equipment brought to the theaters of conflict. The physical and emotional trauma incurred by soldiers and those living in war zones is oftentimes incalculable. 4.1 million veterans who served in wars post-9/11 are receiving medical benefits, among other compensation nearing $199 billion, according to reports from the Department of Veterans Affairs.
