Would this work as a quality thesis statement? Explain

"The united states should change its approach to the war on terror"

No this is not a quality thesis statement because it is to general and nearly impossible to defend. Here's an example.

Don't write: "Eating fast food is bad and should be avoided."

It leaves a lot of big questions to answer. Is all fast food bad? Why is it bad? Who should avoid it? Why should anyone care?

Instead write this: "Americans should eliminate the regular consumption of fast food because a fast food diet leads to preventable and expensive health issues, such as diabetes, obesity, and heart disease."
