Strange but i suppose they want there us Citizens to be protected and there for saying if you want to operate with the US you must sign our agreementMartin,
Social media is another option. If enough people complain, the law might get changed.
The drawback to that is a law can be change back and forth many times. A US Supreme Court ruling that overturns a law is likely to stick a lot longer and sets a precedent that can be applied in other cases of regulatory infringement on the rights of traders.
There's no reason that both avenues can't be tried simultaneously.
