The wall will be eventually built, and there is no doubt about it. That said, less and less Mexicans are immigrating illegally to the US, ever since Trump was elected as the president. The authorities are less tolerant towards the illegals now.
In what century do you live? Who'll stop the wall? Smugglers dug a kilometre long tunnel. And hang gliders? No wall is fake which only works on stupid Americans. An intelligent person would believe in such nonsense.
