I have. Perhaps you should educate yourself on the word.
In this sense it means to "facilitate" and cannot be construed to mean "prevent" or "ban" by any stretch of the imagination.
Oh, you mean we're supposed to "facilitate" the provision of nuclear bombs to people screaming "Death to America," not "prevent" such?
You know, f.Christian is almost more coherent than you are.
No, the federal government is given the power (first posessed by you I might add) to facilitate trade between the various states and foreign nations. The federal government is given no power that you didn't first posess. You don't have the power to prevent your neighbor from trading with anyone. Thus the government doesn't have that power either. (We hold these truths to be self-evident....That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed)
What another country develops is none of our business. Nobody has attempted to restrict us from developing our own weapons and we shouldn't be in the business of deciding what other nations do within their own borders.
