The implications of isolationism in foreign policy can lead to diminished international engagement and potential economic repercussions. Countries adopting isolationist stances often prioritize domestic interests over global cooperation, which may hinder participation in multilateral agreements and international organizations. This approach can result in strained diplomatic relations, reduced influence on global issues, and limitations in addressing transnational challenges like climate change and terrorism. Ultimately, isolationism can compromise national security and economic stability by retreating from the interconnected global landscape.
