Apologies for the late reply. Do you have a source for that request of Merkel's?
You specifically mentioned "forget their role in two world wars". That is not the same as stating the - historically accurate notion - that Germany was not the sole party responsible for WWI. A major instigator, possibly the most important, but my no means the only one.
No mainstream politician in Germany denies German responsibility for WWII.
It's ok, HN doesn't provide notifications, a quick google turned out this link, not the most respectable source I will admit, but I remember it being fairly well reported at the time.
