In matters of foreign policy you have little choice; like it or not, there is plenty voters in this country to empower a government that retaliates when this country is attacked or threatened.
Not according to my constitution. And if it weren't for the income tax, I could certainly refuse to support any incursion on foreign soil that didn't relate to national defense.
That is the essence of both libertarianism and our constitution. The people were allowed to freely refuse to support bad government decisions.
I am disheartened to see you resort to the might makes right argument. Votes shmotes.
