Their gut-level response is to build fences and walls, as long and as tall as possible, whether on the border between Mexico and the US, on Israel’s border with Egypt, or on Hungary’s border with Serbia (or even with fellow EU member Croatia). It is no coincidence that Hungarian and Bulgarian policymakers have turned to Israeli companies to seek technical advice on how to build their fences.
阵线另一侧的群体害怕外来人口对其民族身份构成威胁。无论在墨西哥美国边界、以色列埃及边界还是匈牙利塞尔维亚边界（甚至与同为欧盟成员国的克罗地亚边境），尽可能修建篱笆和围墙是他们本能的反应。匈牙利和保加利亚决策者求助以色列公司寻求围墙修筑技术方面的建议绝不是巧合。
