Israel tries to fortify their borders with a concrete wall that should keep terrorists out. However, as I already argued in the post “Peace Line in Belfast Divides the City”, walls provide only a short-term answer and cannot replace peace negotiations.
And there is yet another problem: Can such a physical barrier really hinder terrorist attacks in the time of modern warfare?
What do you think about a country's attempt to protect their border with a physical wall? Does this really lead to more security?
