Libertarians seem to have a problem right now

And I say this as someone who leans libertarian.

1. There is no such thing as a "free economy" in the real world:

In the real world - regulations have to kick in at some point, or the "winners" of the system can snowball their resources and gain complete control of the system.

There is no such thing as a "free economy"

Communism proves it on one extreme
Private Equity, crony capitalism, and Monopolies prove it on the other

As long as human nature is involved, something will go out of balance eventually.

2. We have a right to protect ourselves and solidify our defenses in our own hemisphere

The Monroe Doctrine isn't some imperialist idea. If a hostile foreign power starts building a military base in the Caribbean or South America, that’s basically in the U.S.’s front yard. It makes the country a lot more vulnerable to things like invasion pressure or blockades.

We need to make sure no major rival can set up shop close enough to become an immediate threat. We have every right to put countries next door to us in their place. You'd think the Cuban Missile Crisis would be enough evidence for this.

Basically, the hardcore libertarians who are crying right now are either retarded, ignorant, or aren't really libertarian at all, but democrats in disguise.
