This has more to do with worldwide propaganda and less to do with changes in the US in particular, and with regard to changes, it probably has a lot more to do with post 9/11 military activity and demographic changes in ally countries than any one particular president or leadership. Also keep in mind their national pride and the propensity for Canadians and Europeans to shit on America as often as they can, which they have been doing for a century or longer. The US has a lot of problems and has had a lot of problems for a long time. The country might not be capable of overcoming some of them, and that also might not be something new. But, going by the strict definition of democracy, it has never been a good model for democracy, by design. The US is a dictatorship of laws, a dictatorship where the dictators are dead. Maybe it was a good champion of liberty for a long time and faltering more brazenly in that role as of the last couple of decades, but that's not the same thing as being a model for democracy.
