1. Comparing Israel to the Nazis is disgustingly anti-Semitic.
2. Comparing Gaza to Dachau is absurd. Dachau's inmates were political prisoners interned by Hitler. Gaza's residents are imprisoned by nobody (except for their own anti-Semitic hatred).
3. Gaza residents are of four basic classes: Hamas terrorists; residents who are not part of but aid Hamas; residents who are not part of Hamas, are sympathetic to Hamas, but stay out of the way; residents who are not part of Hamas and try to stay out of the way. The first two classes of residents carry out and support attacks against residents of Israel as freely as they care to and have the means. The only freedom Dachau residents had was to die.
4. Israel has repeatedly offered "two state solutions"; Hamas, Hezbollah, and the Palestinian Authority have repeatedly refused any solution that does not wipe out Israel and Jews. Israel is not morally equivalent or inferior to Hamas, Hezbollah, and the Palestinian Authority.
5. As Golda Meir is reputed to have said, when the Arab Palis (my phrase) love their children more than they hate Jews, peace will be possible.
