Then why adopt the "libertarian" label at all? President Bush himself has said that the War on Terror will last for at least the rest of our lifetimes. Going by your logic, we will never have time to fight for liberty-based domestic causes. Why not just label yourself a "foreign policy hawk" or a "War on Terror supporter"? They're both perfectly honorable terms and describe your views much more accurately than the "libertarian" label.
Because I want to distance myself from FR's current definition of "conservative", which appears to have taken a turn toward overwhelming government intrusion and ever growing centralized government power, with a bit of religious hysteria thrown in for good measure.
I support a centralized government which directs its energy to national defense,I am pro interventionism in behalf of national security, pro "freer" trade (as opposed to protectionism), and whatever national policy is in the best interest of the nation.
I believe that to solve what those of us on the right of the political spectrum believe to be the important social issues of our times, we need to roll back the powers of the Federal government, and give those powers back to the States.
Let each individual State decide on issues such as abortion, gay marriage, and guns; that's what the Founders intended.
The war on terror will last the rest of our lifetime ONLY if we fight it half assed, and we're doing just that.
