Firing General Neller Might Be A Good Presidential Choice

Shouldn’t President Trump fire Marine Corps Commandant General Neller for insubordination? The General’s stupid remarks that defending the border against illegal immigration poses an unacceptable risk to the Marine Corps are nearly treasonous. He might be a fan of Beto O’Rourke who wants no border security at all so billions of people can volkerwanderung around the United States as they feel the feet move them. 

General Neller may not comprehend that defending the land area of the Unitied (crumbling?) States and the properties of rights and real property is the sole reason for the existence of the Marine Corps. Its purpose isn’t to have high pay and benefits with lots of war gaming and fine equipment to sometimes go kill people in third world countries.

If defending the southern border poses an “unacceptable risk to Marine Corps combat readiness and solvency“, it isn’t good to consider what might happen if the Corps faces a tougher opponent.
