I'm not a tourist. My late father was a holocaust survivor, and one of the things you can do if that is so is apply for German nationality. I did ages ago, so I have EU citizenship.

"“Former German citizens who between January 30, 1933 and May 8, 1945 were deprived of their citizenship on political, racial, or religious grounds, and their descendants, shall on application have their citizenship restored. They shall be deemed never to have been deprived of their citizenship if they have established their domicile in Germany after May 8, 1945 and have not expressed a contrary intention.'"
In the UK, many Jewish children and grandchildren of those stripped of citizenship in Nazi Germany are now applying to Germany for citizenship.
American Jews are also applying.
