What does border barbed wire mean?

Border barbed wire is an artificial physical barrier, which is usually used to isolate the border or the area designated as a restricted area from the outside world. It is mainly composed of steel wire mesh and steel bars, about 3-4 meters high, and aims to prevent threats such as illegal entry, drug trafficking and terrorism. Border barbed wire is usually built in a large area, and it is easy to cross the border illegally or in the restricted area. Different types of border barbed wire have been widely used for various purposes all over the world.

As early as the beginning of the 20th century, European countries began to build border barbed wire to restrict the movement of immigrants, refugees and dissidents. These barriers kept appearing and strengthening until they gradually disappeared after World War II. However, with the development of globalization and the increasing threat of international terrorism, many countries have begun to rebuild border walls and barbed wire to limit illegal immigration and control terrorism. For example, the "US-Mexico border wall" between the United States and Mexico, and the "building border" between Israel and Palestinian territories are all famous border barbed wire projects.

However, the border barbed wire has also brought various problems and controversies. On the one hand, this barrier can effectively limit illegal immigration and international crimes, but on the other hand, it also hinders the freedom of international immigration, asylum and mobility. For example, on the "US-Mexico border wall" between the United States and Mexico, a large area of ecosystem has been destroyed, and the relationship between the United States and Mexico is tense, which costs billions of dollars. Therefore, whether to set up border barbed wire and how to safeguard national security and international cooperation need to be fully weighed and negotiated.
