3. FDR
2. Lincoln
1. Dubya
This list (in its entirety) is why I could never be a full on Libertarian. Foreign policy is ridiculous and for the most part their social policy is as well.
So your issue is with the peace and liberty part, not the complex economic theory part?
As always, it's not as simple as nice little buzzwords like "peace" and "liberty". Take the Civil War for one. The list puts Lincoln in the top ten worst for obvious reasons, one of the largest being that he started a war against the right to seceded, etc. While the "right to secede" might sound well and good, practical reality says otherwise. Fact is, a nation can not survive when a large chunk of it can just decide to leave simply because it doesn't like the result of an election. If that happens, that sets a horrible precedent that can not be tolerated. As President, one's duty is to ensure the survival of a nation, and if a man (or woman) with such a duty allows something on that scale to happen, they're not doing their job and have betrayed their duty. As well, it leaves America a much weaker nation, open to complete dissolution. Of course, Libertarians would just
love that. As well, a Libertarian foreign policy doesn't cope with the reality of something like the Cold War. It would be disastrous for a country merely to ignore a conflict and allow a nation like the Soviet Union to gain the upper hand on the world stage while America gets to talk about how "Libertarian" it is, without its nuclear weapons and whatnot. Continuing, the arms race was a necessary deterrent from a large war that would've resulted in millions dead and many countries wastelands.
