Defense size and structure we can debate, but we must not lower our strength or vigilance. "Defense" can be characterized as protection from attacks from other powers, space, cyber warfare, domestic attacks by foreign theocracies (ala 9/11), strategic assinations.. to a China who has a 200,000,000 man army and is building super carriers while we speak.
In any case..one of the few mandatory charges to the federal government by our CONSTITUTION is to "provide for the common defense".... I see no provisions in the constitution which call for providing the following extravagances:
A) The National Endowment for the Arts..
B) The Corporation for Public Broadcasting.
C) National endowment for the Humanities
D) Taxpayer funding of public union activities.
E) Covering just the administrative costs for Obamacare ($900,000,000)
F) Maintaining forever, the "mohair subsidy".
We all should realize by now, that we cannot get it all at once... so let's start with this list of totally useless expenditures..remove them..and then start paring on the essentials..
