"National isolation breeds national neurosis"

This quote by Hubert H. Humphrey recommends that when a country isolates itself from the remainder of the world, it can lead to psychological problems. Seclusion can cause a lack of understanding of other cultures, which can cause fear and skepticism of those beyond the nation. This can lead to a sense of paranoia and insecurity, which can manifest itself in a range of methods. For instance, a nation may end up being extremely protective of its borders, or it may become extremely aggressive in its diplomacy. In addition, isolation can result in a lack of understanding of the world beyond the nation, which can cause an absence of understanding and understanding of international issues. This can lead to a lack of empathy and understanding of other cultures, which can result in more isolation and skepticism. Ultimately, isolation can cause a country becoming significantly aberrant and paranoid, which can have a negative impact on its people.
