A median of 57% across the 11 NATO member countries surveyed voiced favorable views of the coalition, with only about a quarter (median of 27%) expressing negative opinions.

The alliance’s strongest support among the countries surveyed comes from the Dutch and Polish. However, an overwhelming majority of Greeks express negative views, setting them apart as the most critical member of NATO included in the survey. Meanwhile, Americans regard NATO favorably by a more than two-to-one margin.

When asked if being a member of the post-World War II security alliance was good or bad for the U.S., 77% said it was a good thing. Only 16% said membership was a bad thing.
