Final answer:
The importance of international trade gains often varies by country size, with small countries typically benefiting more due to their limited resources. Historically, a few countries have had outsized influence on international laws. Today's global challenges highlight the complexities of cooperation without a global governing authority.
Step-by-step explanation:
The question appears to be exploring ideas related to leadership, international relations, and the complexities of international trade. The suggestion of leaders 'practicing' on small countries before leading larger ones is oversimplified and does not take into account the vast differences in political, economic, and social dynamics between countries of various sizes. However, discussing the gains from international trade is crucial in understanding how both large and small countries navigate the global economy.
Small countries often find the gains from international trade to be relatively more important because it allows them access to a wider variety of goods and services, technology, and investment opportunities they may not be able to produce or obtain domestically. Large countries, while also benefiting from trade, have more expansive internal markets and resources, which can sometimes lessen the relative impact of international trade on their economies.
The issue of global collaboration and decision-making is significantly more complex. Historically, a small group of countries has exerted considerable influence over international laws and trade, which raises questions about legal rights and historical actions, such as colonialism. Today, global challenges, such as climate change, require unprecedented levels of international cooperation. The absence of a global governing authority creates a situation where individual national interests may override collective good, thus raising the question of whether a route to global acceptance of a plan is possible without some form of global governance.
