Explain what is ment by the swelling of the pentagon
The Pentagon is used to represent the entirety of the United States Department of Defense (DOD). This would make the swelling of the Pentagon a reference to the swelling of the DOD. Depending on the context, this is most likely specifically aimed at the Department’s budget/spending.
In August, 2011 Congress passed, and President Obama signed, the Budget Control Act. In doing so, they are requiring a $1.2 trillion cut in federal spending over the next ten years. The Department of Defense specifically must cut its budget by 13% to comply with this financial regulation. The proposed 2013 DOD budget is $613.9 billion.
