2) Participants weren't asked if we were any ally, they were asked if we were "an ally - that shares our interests and values". Shared values have little to do with what an "ally" means in the common parlance.
3) Excluding the full context could give you a false idea of how they view us. The full results:
16% - An ally—that shares our interests and values
51% - A necessary partner—with which we must strategically cooperate
13% - Don't know or refuse to answer
12% - A rival—with which we need to compete
8% - An adversary—with which we are in conflict
4) The idea that Europeans don't see us as allies is belied by their answer to the question "At the current time, would you support or oppose developing an alternative European nuclear deterrent that does not rely on the US". Only 16% strongly supported it. So they don't "see us as an ally", but they're happy to rely on us as their strategic bulwark? Hmm.
5) In my mind, the only question that actually matters on this survey, w/ regards to the opinions of our European friends, was this one: "If your country was forced to choose between being a part of an American or a Chinese bloc of countries, which would you prefer it to end up in?" Sadly, European responses to that question were not provided! If anyone delves into the underlying data, I'd love to know the results for this question.
