Final answer:
The statement is true; the American Revolution inspired other independence movements with the successful signing of the Declaration of Independence. However, it also brought internal conflicts and suffering to the new nation.
Step-by-step explanation:
The statement that the American Revolution started a domino effect because other nations saw that the colonists were able to gain independence and wanted the same is true. The American Revolution was a pivotal event not only due to the formation of the United States but also due to its inspirational impact on other nations' pursuits of independence, liberty, and happiness. While the war had various driving factors including economic, political, and ideological disagreements, it unified colonists of different backgrounds against British rule. The success of the Revolution and the subsequent creation of a new nation based on principles such as popular sovereignty, albeit imperfectly realized, provided a powerful example for other movements of self-determination worldwide.
Despite the complexities and internal struggles during the revolution, the signing of the Declaration of Independence marked a significant point in history as it was the first of its kind to be successful. It set a precedent that influenced later revolutions and independence movements across the globe. However, it's important to recognize that the revolution resulted in internal conflicts about the nature of the new nation and caused suffering for many, including not only soldiers but also civilians.
