I just like how Trump says we have to learn the lessons of 9/11 and proceeds to ban people from countries that had nothing to do with 9/11 while not banning people from countries that did.
So, if we were to learn things from the occurrences in the Cold War, such lessons would only be applicable to another conflict with Russia?
You miss the point. The countries that the hijackers originated from are not considered “sponsors of terrorism” now and weren’t then either.
Trump has either neglected banning those countries now do to incompetence or political reasons.
Don’t forget (personal) financial reasons.
