Political commentators see recent policies of the government toward Country X as appeasement, pure and simple.
Conclusion
This view is fundamentally mistaken. (i.e. recent policies towards Country X are not just appeasement)
Evidence (for)
Polls show that most people think that recent policies toward Country X are not appeasement.
Evaluate
The author is trying to convince us of her conclusion that certain political commentators are wrong.
The only evidence she offers is that according to polls, most people think that these political commentators are wrong.
What's wrong with that?
We have no idea if most people have any idea what they're talking about. Polls may show that most people think that "there are penguins at the North Pole", but that doesn't mean there are penguins at the North Pole (there are not; they live near the South Pole)
Goal
Let's look for an answer calling out the fact that an author isn't allowed to assume that just because most people believe A is true, that therefore A is true.
Some people would call this a semi-famous flaw known as Opinion vs. Fact
