EVERY US citizen, corporation or entity has the Constitutional right to free, unrestricted trade with any foreign country subject to trade regulations, import restrictions and import duties as levied by congress.Fixed it. So you'd be wrong again. But then it is your style to lie and make a fool out of yourself.
So were you into trading with North Vietnam during the 1960's? Jane is that you?
And OUTSIDE trade regulations, import restrictions and import duties as levied by congress, EVERY US citizen, corporation or entity has the constitutional right to free, unrestricted trade with any foreign country.
