The whole article is nothing else than an antisemitic propaganda. Most Germans don't feel comfortable to be Germans - that's the whole background of such a bullshit. This left kind of antisemitism is an open secret for everyone who is living in Germany.

If Israelis hear Germans discussing about that Germans don't like to defend Israel with weapons - I think they just will be happy about and laugh like crazy, because Jews anyhow don't like to be defended from Germans as in the years 1933-1945 they were defended from Germans. But perhaps only 10-20% of all Germans would defend their own country Germany with weapons.
