Why is libertarianism so infallible?

Libertarianism is the inclusion of every sapient being into the decision making process and all that logically follows from that. Utilitarianism is the objective of ensuring the most happiness for all sapient beings and all that logically follows from that. Sometimes they compliment each other, other times they contradict.

how does a person claiming bush is a socialist make libertarianism bunk?

I don't see bush as a socialist, I am not american and I don;t follow american politics close enough to know bush's stance on every issue. I do know that he was responsible for various tax cuts and is generally opposed to big government. On the other hand, fighting a war in iraq is not a libertarian act. Does communism tend towards war, I would say yes on the grounds that communism is usually statist. Of course, communism is not necessarily statist so pursuing acts of war does not make one a communist.
