You seem to be seeking the moral high ground for justifying a country's exercise of its ability to curtail immigrants. As the responses are showing, the moral high ground is largely unavailable for this particular motion. On the other hand, a country can do what the heck it pleases on letting people in, which is generally the bedrock of its powers anyway, so why is this an issue.
