"Building walls isn't going to work in the long run. Some people are happy with the wall in Israel, but somebody will get a weapon someday and knock it over or something. Walls aren't the answer between countries, though"

In this quote, Arlo Guthrie is providing a critique of making use of physical barriers, or walls, as a long-lasting solution to political or social concerns between countries. The essential message suggests that while walls might provide a sense of security or a temporary option, they are eventually inefficient in resolving the underlying problems that cause their erection.

First of all, Guthrie brings up the example of the wall in Israel. This specific reference most likely points to the Israeli West Bank Barrier, which was constructed with the intent of improving security and avoiding attacks. In pointing out that "some individuals are happy with the wall", Guthrie acknowledges that there are fans who believe it serves a helpful function. However, his follow-up-- a prediction that "somebody will get a weapon someday and knock it over or something"-- suggests hesitation about the barrier's long-lasting durability and effectiveness. This recommends that walls can be physically breached or symbolically overcome, stopping working to provide a long-lasting option to the conflicts or concerns they are suggested to deal with.

The wider argument Guthrie makes is that "walls aren't the answer in between countries". By this, he implies that walls represent an oversimplification of complicated geopolitical and social problems. Walls function as a physical manifestation of division and isolation, rather than attending to the source of tension, such as financial disparity, political dispute, or cultural distinctions. Guthrie's point of view highlights the idea that sustainable options require discussion, collaboration, and understanding, rather than physical separation.

In essence, Guthrie's message is a call for more detailed and humane methods to international relations. Rather of erecting barriers, nations need to seek to develop bridges through diplomacy and good understanding. By doing so, they can work towards solutions that cultivate peace and cooperation, standing the test of time better than any constructed wall ever could.
