Both sides are wrong on the issue of isolationism!
Libertarians are wrong because without strong military power projection worldwide no one can be a super power, and we need a moral super power to keep order in the world. We do not want to go back to the time of ancient conquerors such as Tamar Lane, Chengiz Khan, Alexander of Greece, etc when any marauding force could plunder any lands. We do not want Saddam Hussein to plunder Kuwait, then Saudi Arabia. We do not want Iran to plunder Iraq and other oil producers.
However libertarians are also right in that a super power can not maintain that status by borrowing money to project military power. At the present time, we are broke and in debt to our eyeballs, soon to join Greece and Italy & Spain. So, at present time, we have no choice except to shrink our foreign military involvement. But we can never follow Ron Paul’s libertarian agenda permanently. That would guarantee a second class country.
Anyone that thinks China will be a benevolent super power is deluded.
The US is not responsible for maintaining order in the world.
That is the neoconservative’s foreign policy.
True conservatism is for limited government, including the use of the military.
We are not the world’s cops.
