In his 2008 campaign, candidate Obama promised to develop a civilian agency with the same budget and power of the Defense Department.
That had already started, but was spread over much of the Federal Government:
“Former U.S. Senator Tom Coburn (R-OK) … points out that, ‘In the nine years until 2014, we found 67 agencies unaffiliated with the Defense Department bought $1.48 billion in weapons and ammunition. Of this total, $335.1 million was spent by agencies traditionally viewed as regulatory or administrative, such as the Smithsonian Institution and the US Mint.’”
Back in 08, somebody in the Obama administration truly believed in the need of a "civilian" agency as armed and as numerous as the Defense Department.
