Legalized drugs
Better than the current FU'd situation now
Open borders
Borders are already open. Libertarians would eliminate the welfare state and the handouts, illegals would have no incentives to come here
No action against terrorists in other countries
We'd respond if attacked. We just wouldn't be doing all that "spreading democracy" crap in the ME.
Of course illegals would have incentive to come here. It's called work. They would work for less than legal residents just like they do now. Do you want us to go back 100 years in our standard of living?
