The problem with a wall or a fence - and I think this would be more like the Great Wall of China than the Iron Curtain - is that people will continue to find a way in as long as there is incentive for them to do so that outweighs the potential risk and consequences. Unless and until that changes, no wall, fence, or law will be effective, and we will continue to pour resources into preventing illegal immigration that could better be used elsewhere - for the benefit of current citizens, instead of the detriment of illegal aliens.
This is true. But it doesn't need to be an absolute success if it minimizes to a large enough degree the number of illegal aliens who risk the trip. As many as now come across the border, there are many who don't because of the danger, the cost, or other considerations. Some will still find a way to get through, but the number will likely be smaller because of the increased risk, cost, etc.
