Doesn’t matterSo when talking about the wall the left likes to imply that it won't serve any practical purpose. "People will dig under it, climb over it, fly over it and some of them will even blah blah blah..."
Yes, you are correct that a wall won't be an absolute solution to the problem of illegals crossing the border, but it's outright dishonest to say it won't at least be a powerful deterrent. It won't stop all of them, but it will stop some or many of them. Walls work, and there are a lot of modern examples that demonstrate that truth.
We will tear down the wall once Trump is gone
Mexico may even pay for it
Bet you don't
