1. Lack of Unity and Central Authority: The absence of these four states would have weakened the unity and strength of the new nation. A divided nation with varying political and economic interests could have led to conflicts and instability, making it harder for the central government to govern effectively.
2. Economic Disruption: The four non-member states could have posed economic challenges to the union. They could have imposed trade barriers or chosen not to participate in the common market, which would have disrupted interstate commerce and hindered the growth of the national economy.
3. International Relations: The exclusion of these states would have made it more difficult for the United States to negotiate with foreign nations and establish diplomatic relations. Other countries might have been less willing to recognize or engage with a nation that was not fully united.
4. Political Instability: The potential for regional rivalries and conflicts could have increased if the non-member states developed their own alliances or pursued independent foreign policies. This could have led to political instability and internal strife within the union.
5. Setting a Precedent for Secession: The decision by these states to remain outside the union could have set a precedent for future secessionist movements. Other states might have been tempted to follow suit, leading to the fragmentation of the nation and undermining the idea of a unified republic.
6. Loss of Territory: The exclusion of the four states would have resulted in a significant reduction in the territory of the United States. This would have weakened the nation's bargaining power in territorial disputes with foreign powers and limited its access to natural resources.
By having all thirteen original states ratify the Constitution, the new nation was able to establish a strong central government, promote economic development, negotiate effectively with foreign powers, and maintain its territorial integrity. The inclusion of all states strengthened the union and helped lay the foundation for a prosperous and stable nation.
