Not in a democracy. Not unless they utter the magic phrase 'national security'.
Oy! If your defence comes down to "we're not as bad as X dictatorship", then you have already lost the debate.
For the record, my criticism of US is strictly limited to US foreign policy (and it's effects on human rights). I have always maintained that the US society in general, and the US Constitution in particular, are the gold standard for human rights. Most countries in the world would do well to emulate them. However, the fact remains that those liberties are under attack in the US.
I am hardly the only one making this observation. There are plenty of people within American concerned about the trend.
Oh geez. Just google 'secret evidence' or 'cipa secret' and there's a ton of material.
All true, but irrelevant. We are not debating citizenship in general, but in the context of people who are deemed to be hostile to US interests. You took half my statement. I wrote "For people who are real bad guys, citizenship is irrelevant." In other words, if someone is a real threat, they will be locked up regardless of citizenship. So this proposed law has no impact on the real bad guys.
