I have read a lot of comments regarding Trump’s wall, pro and con. Some critics have noted that the wall is static and a static solution to a problem loses value as time goes on. Just like cybersecurity, if it is not dynamic and undergoing continuous upgrades, “bad guys” like Putin will find a way to breech any static security. I have yet to see any security experts give a cost-benefit analysis of having a wall, to solve the problems that Trump thinks his wall will solve.
