Tom Woods recounts how Murray Rothbard convinced him that Peace and Liberty cannot be severed.
"It's Memorial Day weekend, a time when we (hopefully) reflect on war rather than celebrate it. So, it's the perfect opportunity to revisit an inspiring antiwar talk from our own Senior Fellow Tom Woods.
You may not know it, but Tom was once a neocon who considered the libertarian position of noninterventionism unrealistic and naive. But, his mind was changed by none other than the late Murray Rothbard, who convinced Tom that peace and liberty cannot be severed, that empire abroad leads to socialism at home, and that foreign policy should be front and center in a libertarian worldview."
