I am not making any claim that there is imminent danger. IF you read what I said "Is it just remotely possible that President Trump received a security briefing that indicated that the countries affected by this EO had a high security risk?" Do you see any claim that we are in imminent danger?
The best way to fix this is for President Trump issue a new executive order that does the same thing but carves out exception for those that currently have green cards or visas. That can not be challenged in court. Well it could, but has no legal standing.
There are many things remotely possible, like Russians influencing the election and we have a president that was elected under falsehood.
Are we done now with remotely possible assumptions?
Maybe I just don't know the US system well enough, but I believe Trump has other ways to escalate defense if he truly has Intel on potential attacks. He at least has to understand that without proper evidence, a court of the law cannot act on presumptions. You and I understand that, right?
[Edited] Concerning your suggestion on the visa, well, Trump needs to work things out a bit further now...
