Well duh! The question is, do you think it helps the argument to try and link them to Nazi's or do you think it immediately turns off 90% of the population who are tired of hearing about how everyone we don't like are Nazi's. I've heard Bush is a Nazi, Clinton is a Nazi, Gore is a Nazi, Cheney is a Nazi, Buchanan is a Nazi, etc, etc. The broad stroke of Nazi means nothing today and in fact it turns people away from the facts.
Arabs want to destroy Israel (and America by the way, it's not just Jews). Rather than just paint them with the broad brush of Nazi, we need to change their minds and heart by introducing freedoms and government reforms and overthrow. Eradicate the terrorist population and bring free enterprise to the region. There will always be the anti-Israel, anti-US groups but we can make them fringe groups by bringing a "middle-class" that is dependant on trade with other nations.
You’re right, Bush isn’t a Nazi, nor is Clinton, and I’d agree the constant use of the term demeans the enormity of the evil of National Socialism.
However the connections between National Socialism and the Muslims of the Middle East and Eastern Europe, jihadists and Baathists too, is a historical fact. Recognizing the NAZI roots of their worldview, and their wahabbi roots, is certainly relevant if you wish to change their “hearts and mines”.
