I would like to get some input from China, how long did their wall help?
Maybe a word from Ceaser Hadrian too.
As long as the US is so greatly more prosperous than Mexico , we will have some people useing whatever means it takes to get in reguardless of the danger.
Consider that a 90 and a 150 mile wide moat infested with sharks is not enough to prevent Cubans and Haitians from makeing the trip , is the wall going to be harder to cross than that?
