It doesn't. And especially not with a treaty that only affects international trade.Since when does the piece of crap UN over rides our constitution?
Recent history has proven that "international trade" treaties have had a detrimental effect on America and her economic power and clout. I don't give two hoots what Europe thinks is best for America. I care about what our Founding Fathers believed. Jefferson was totally opposed to "foreign entanglements."
"Recent history" has shown that the Hard Right are wrong on this issue. They want the criminals armed because that is a great way to scare everyone else to buy guns. Now they want the Warlords/Terrorists armed as well, we can then pay for a war to fight them...
