In a way, I have to agree with her. The US spends way too much time and taxpayer money telling other countries (either on its own or through the UN) how to take care of business, or protecting one country from another.
I don't like the idea of some countries having certain weapons, but its not our place to tell them they can't.
The Constitution does not provide for that kind of authority.
If they told us WE couldn't have them, what would the reaction be?
But we're not our using our weapons to terrorize people for no good reason.
