The claim that is not defensible is:
OD. The world would be better off if political boundaries didn't exist.
1. Decreasing taxes on middle-class citizens improving the U.S. economy is a defensible claim because it can stimulate consumer spending, which can boost economic growth.
2. The nation's debt generally rises during times of war is a defensible claim as well, since wars often require increased government spending, leading to higher debt levels.
3. The claim that the government works better when the president and the majority of Congress are from the same party can also be defended based on the potential for smoother cooperation and implementation of policies.
4. However, the claim that the world would be better off if political boundaries didn't exist is not defensible. Political boundaries serve important purposes such as defining territories, establishing governments, and maintaining order among nations. Removing political boundaries entirely would lead to chaos, lack of governance, and potential conflicts over resources and territory.
