As a western European, most of it is associated with the current president and administration. Almost every European liked Obama and supported his international leadership.
I think it's fair to say that Obama was much more trusted in Europe than either Bush or Trump. When you break it down by country the story is more complex, but the poster did admit to being western European.
My own experience is that nobody cared about Obama (and the ones that came before him) but the media are trying their hardest to report any negative news about Trump.
You are making some strong statements.
