Maybe if you listened to the words of these politicians, you’d come off with a different view of them. The CDU in particular have confessed to having a particular passion for a united Europe. Their continent-wide influence cannot be denied at this point.
Strange thing, that one of the wealthiest and most populous countries in europe has some influence in the political theatre of the EU.
For the most part Germany is just the most visible part of a block of nations with more or less the same agendas (BeNeLux, Austria, Denmark, Sweden, Finland and recently Poland and the baltic nations) and still they need one of the other big 4(UK, Spain, Italy or most likely France) to achieve the influence they currently possess.
There is more than one view of europe inside the CDU/CSU there is Schäuble, who is affected by Kohl, and the more sceptical faction of Seehofer or even more extreme Bosbach, Steinbach et al.
And inbetween is Merkel and her clique of secretaries who see the EU as a necessity to be able to compete with USA, China, India, Russia and Brazil in the future
