Why is over reliance on international trade a very bad strategy?

Over-reliance on international trade can expose a country to significant economic vulnerabilities, including fluctuations in global markets, supply chain disruptions, and geopolitical tensions. It may also lead to a loss of domestic industries and jobs, as local producers struggle to compete with cheaper imports. Additionally, such dependence can hinder a nation's ability to achieve self-sufficiency and resilience in times of crisis, making it more susceptible to external shocks. Ultimately, a balanced approach that includes robust domestic production is essential for long-term economic stability.
