This isn't even close to the same thing as the Chinese government banning their own citizens from using Chinese services and infrastructure because of "bad social behavior".
I didn't say the US shouldn't let people in or be respectful of foreigners - I was just stating the fact that they do not have any legal obligation to do so. Of course they do it because it is good for the country - but if they stop, who is going to make them change their mind? It's up to the American people to decide what they want for their country at any given time - the rest of the world has no power to make them do otherwise - as does any other country and I wouldn't want to force any country to take people they don't want to either.
A country with many allies is much more powerful than a country with none. This is a lesson that is taught before children enter school (play nicely with others), I don't know how this became an American attitude and I find it very disappointing and worrisome.
You often hear statistics like the US fund 25% of NATO, or something similar. I don't see how this is a bad thing, this means we have 4 times as much power than if we were not in NATO, because we supply the most we have the most control over the group, and because we play nicely with others and listen to the needs of other countries who have similar morals as we do.
You are the only one talking about a legal obligation, the article and everyone else is just talking about how this is not the behavior the world and US citizens would not like to see coming out of America the melting pot.
> Your comment sets up a pointless argument in that of course no country is required to admit anyone, but reasonable policies invite good reciprocal treatment.
All I said was that the US has no obligation to do anything for outsiders. I didn't say they shouldn't and obviously they do - just don't expect some kind of natural right to be accorded to you if you aren't a citizen of their country.
