Think of what could have been done with the at least $6.4 trillion that has been wasted on senseless wars. From Mike “Mish” Shedlock at moneymaven.io:

Summary of War-Related Spending
Changing the Names of the Wars to Hide the Total
One potential barrier for civilians to understanding the total scale and costs of the post-9/11 wars is the changes in the naming of the wars. The US military designates main war zones in Afghanistan, Pakistan, Iraq, and Syria as named operations. The longest war so far, in Afghanistan and Pakistan, has had two names: Operation Enduring Freedom, designated the first phase of war in Afghanistan from October 2001; it was designated Operation Freedom’s Sentinel on 1 January 2015. The war in Iraq was designated Operation Iraqi Freedom from March 2003 to 31 August 2010, when it became Operation New Dawn. When the US began to fight in Syria and Iraq, the war was designated Operation Inherent Resolve. For ease of understanding, the costs are not labeled here by their OCO designation, but by major war zone — namely Afghanistan and Pakistan, and Iraq and later Iraq and Syria.
