In a sense he was right. Unless you are very, very conservative in much of the non-US West that were not part of the former Soviet empire - i.e. Canada, Germany, New Zealand, Norway but not Czech Republic for instance (and not conservative enough to have fallen into the nationalist and anti-American Right), you will have sneered at Reagan's legacy.
I personally feel some American liberals feel the same but can't express their true feelings at public because they know doing so will make their political future toast - after all, they are in the United States! Foreign left-wingers (or "centrists") and the far-left Americans have no such inhibitions so they feel free to say what they truly think about Reagan.
But they take extreme care to never spout ther anti-USA views up close and personally.
