I know a feminist who was long an active opponent of the Taliban's opression of women, long before 9/11. But her opposition never included a call of an invasion of the country for that reason. Today, she supports the invasion of Afghanistan, but for a different reason altogether. She is bitterly opposed to the Iraq invasion. There is nothing contradictory or hypocritical about these positions.

Invading a foreign country, unless it represents a direct and obvious threat to one's own security is just plain wrong. Even the "direct and obvious threat" is open to interpretation and vulnerable to conflict of interest questions. Likewise, subscription to this policy of non-intervention, does not necessarily imply agreement with that country's policies or conduct, which may indeed be barbaric.

I own firearms, and I believe I have the right to use them to defend my home with deadly force. It does not give me the right to shoot people who are no threat to me, no matter how criminal or dangerous they may be to others. This is why we have laws, (and international treaties) so that we can act with some sort of collective legitimacy in those cases where someone hasn't actually battered down our door in the middle of the night.
