the War on Terror on September 20, 2001, in a speech to Congress. "Our war on terror begins with al-Qaida," he said, "but it does not end there.

 It will not end until every terrorist group of global reach has been found, stopped, and defeated." 

Spending for the War on Terror includes three major components. First, is spending for Overseas Contingency Operations. Congress appropriates these emergency funds, and they aren't subject to budget limits such as sequestration

Second are the significant increases in the base budget for the Department of Defense. Third are the additions to the Department of Veterans Affairs budget to treat wounded soldiers. 

Spending rises along with the number of boots on the ground for these two wars. It also beefs up the domestic force that supports foreign operations. It develops new technology, such as the F-35 fighter jet and drones.

The U.S. military budget includes the DoD and VA base budgets and the OCO. It also includes supporting departments, such as Homeland Security, State Department, and the National Nuclear Security Administration.

Who Spent More, Bush or Obama?

President Bush is responsible for the budgets from FY 2002 - FY 2009. He also added $31 billion for the War on Terror to President Clinton's FY 2001 budget. The total for those nine years is $1.161 trillion.

President Obama campaigned on defense reduction. He even dropped the phrase "War on Terror." He received the Nobel Peace Prize for pulling troops out of Iraq in 2011. But his spending on the Iraq and Afghanistan wars still totaled $807 billion. That's 30 percent less than President Bush's expenditure. Spending was dictated by Bush's and Obama's economic policies.

President Trump campaigned on increasing defense spending. He added $30 billion to the FY 2017 budget. His FY 2018 budget will add another $127 billion to the War on Terror, for a total of $157 billion.

Effect on the U.S. Economy

The War on Terror added $2.1 trillion, or more than 10 percent,  to the U.S. debt.

The  than the Vietnam War. More important, it killed 4,488 U.S. soldiers and wounded 32,226 more. Taxpayers spent more than $800 billion on the Iraq War alone. 

The real cost of the War on Terror is not just what it has added to the debt. It's also the lost jobs that those funds could have created. Every $1 billion spent on defense creates 8,555 jobs and adds $565 million to the economy. That same $1 billion given to you as a tax cut would have stimulated enough demand to create 10,779 jobs and put $505 million into the economy as retail spending. $1 billion in education spending adds $1.3 billion to the economy and creates 17,687 jobs.

That $2.1 trillion spent on the War on Terror created 18 million jobs. But if it had gone toward education instead, it would have created almost 38 million jobs. That would have helped end the recession sooner.
