I shall have much more to say about this in the near future but for the moment let me note that I am increasingly concerned about the soft-core forms of Holocaust denial one sees particularly in Europe.
Calling Israelis Nazis, comparing Israel's actions to genocide, and other such comments, show an ignorance of both contemporary and WWII history.
Whatever you may think about Israel's policies vis a vis the Palestinians, to compare it to the Holocaust is to distort what is going on today as well as what went on during WWII.
This picture, taken in Malmoe, the third largest city in Sweden, says it all. It reads
1941 Zyklon B 1945 Nuclear bomb
1965 Naplam 1983 Mustard gas [Iran/Iraq war?]
2009 White Phosphorous
[Thanks to Stéphane Bruchfeld for bringing this to my attention. He adds that the demonstration was by youth who clearly did not make the banner. Adults did.]
