Legal resident != Citizen. Until you have citizenship you can be sent back at any time for any reason. People get sent back or denied entry all the time for various reasons. What he did sucks but the media is making it out to be a much bigger deal than it actually is. The number of people "trapped" overseas is probably in the hundreds.

We're bombing people in almost every country on the list, so I have no idea why this wasn't done years ago.

No, you cannot be sent back "at any time" "for any reason" as a lawful permanent resident of the United States. I don't know what made you believe that.

What you are saying is contrary to what immigration lawyers say to their clients. Do you have a citation from the Immigration and Nationality Act that says that Congress needs to decide whether CBP officers have discretion to turn back legal residents at a port of entry? To my knowledge, this is the prerogative of the president, and this is exactly the legal basis that underlies Trump's executive order.

Do you have a green card? Cause I do, and the parent is right. It is not a guarantee of being allowed to enter the US, it can be revoked unilaterally by the government.

Of course, in practice it's rarely done without cause (e.g. committing a felony), but in the texts it is clearly stated.
