I think - but will obviously be corrected..
That when it comes to things like gambling - you know, stuff that can really do some damage to those with a tendency to get addicted to that sort of thing - then it really should be ok for a country to say "no thanks" when a business makes it a little too easy to access.
On the other hand that only applies if you have the same rule for domestic businesses - and this I think is where the US is having a few problems. That is they only seem to think that gambling online using a foreign bookie is dangerous. No doubt their own chaps give the money back if they think someone just spent the mortgage payment on a horse race.
We should be fair though, most countries are a little bit naughty when it comes to making stuff up to help politicos look good back home - but when you're called on it perhaps you should have a better answer than "when we said we'd sign up for fair trade practices with our international partners, we meant everything except online gambling."
It's sort of like signing up for the Geneva Conventions, then saying later that you didn't mean the bit about torture. Now who was called on that recently, it's right on the tip of my tongue?
