Once we also abolish most of the double-digit federal law enforcement and military agencies, we can put these duties in the hands of the more streamlined enforcement wing of the federal government.

Ok, so you want to create an entirely new bureaucracy? Department of Homeland Security 2?

I don't want to create anything. But since we don't live in a libertarian utopia, I would abolish the current federal agencies and streamline the whole process. Giving border control to the states would be good. But that also is not a reality.

The most important and essential job of the federal government is to prevent foreign invasion and do customs and immigration enforcement, ICE should probably be the only federal law enforcement agency, that a Navy and an agency to regulate interstate commerce.
