There can be a wall...Congress would probably never fund it anyways, but it can be built if we wanted to. Actually I read last week some architecture organization is having a contest for designs for the birder wall and the winner with the best concept gets 5,000 dollars. It’s a world wide contest.
I want to start a contest for the best non-jackboot method of getting the illegals out of the US.
A competition - with a pretty good prize.
