Hadrian's Wall protected the Roman frontier in Britain for centuries.
Without the Walls of Constantinople, the Eastern Roman Empire would have fallen in the 700's instead of lasting until the 1400's.
The Great Wall of China helped protect northern Chinese frontiers for centuries.
Are walls 100% effective. Of course not. Nothing is. But walls can be a useful part of a strategy for regulating/protecting your borders.
That is not to say that a wall along the Mexican border is advised. It is a very long border, and individuals and groups of smugglers are able to get around an unguarded wall. However, to absolutely dismiss the utility of walls on principle is incorrect.
- 8note 8y agois it still the 1400s? how frequent did planes land in Britannia from the picts? more recently, how'd the Maginot line go? what makes defence against warring enemies similar to preventing immigrants?
- RcouF1uZ4gsC 8y agoIn regard to planes, planes in general are a lot more expensive, fewer, and thus easier to track than are people on foot. Regarding the Maginot line, it actually forced the Germans to use the Ardennes. This was a high risk move for the Germans and if the French had been doing what they were supposed to be doing, they could have destroyed the German Army in the Ardennes. So, the Maginot line actually was useful, but the French failed to exploit what it was doing for them.
- vorpalhex 8y agoI was actually thinking about Hadrian's wall when I wrote the above! The building of the wall was a super expensive task for the time, and it usurped a ton of manpower (they also had the advantage of using slaves for a lot of it, and it still was expensive). Plus once Hadrian's wall was no longer well manned (once Hadrian died), it became a haven for the picts to launch their raids from and a border through which they couldn't be chased.
