That political hack general probably approves. Mattis has been outed as a leftist political puppet who is part and parcel the problem with today’s military brass. They all should be reevaluated and booted out of the service if they are marxists or Marxist sympathizers.
Before anyone enlists or expects a commission the need a short orientation on what the US Constitution is, and why America is exceptional.
It could simply be:
Rights come from God, not government
All Men are created equals, not in ability or wealth, but before the law
Government derives it’s authority from the consent of the Governed, the individual is sovereign
The people have a duty to restore the Constitutional Government, and their natural rights, by force.
If you are not willing to die for these Ideas, the foundation of the American Nation do not take the oath.
