Actually, the problem with the Libertarian platform -- particularly in regard to international relations -- is that it pretty much requires everybody to agree to play by the same set of rules.
Once somebody leaves the reservation, however .... libertarian ideals prevent one from taking any sort of pre-emptive action. And thus you're left with stuff like Ron Paul's ultra-stupid comments to our own doug from upland, concerning what he would not do if Nort Korea was determined to be shipping a nuke to Iran.
It's not the only such stupid comment, but our Friend DFU did a fine job of putting it so nicely in the open for all to see.
“Actually, the problem with the Libertarian platform — particularly in regard to international relations — is that it pretty much requires everybody to agree to play by the same set of rules.”
Or, to put it slightly differently, the libertarian platform only works if everyone is a libertarian.
You can see this in Ron Paul’s positions on Al Qaeda, ie, the only reason they attack us is that we are over there and if we leave ‘over there’, they will not attack us ‘over here’ anymore. This is a the classic mistake of attributing your thoughts and motives to some one else.
