As the founding fathers of the United States of America made clear in the Declaration of Independence in 1776:
"...Governments are instituted among Men, deriving their just powers from the consent of the governed, that whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or abolish it, and institute new Government..."
The US continues to suffer economic difficulties stemming from the federal government's neglect to reform spending. The citizens of the US suffer from blatant abuses of their rights such as the NDAA, the TSA, etc. To withdraw would re-secure their rights and liberties in accordance with the original ideas and beliefs of our founders which are no longer being reflected by the Federal government.
