Shalom,
It would behoove us to learn lessons from Rabbi Kahane's Torah. Considering we are barely holding onto a 'Jewish State' at the moment, and shift to the left concerning the national character of Israel would be tantamount to abandoning the Zionist dream.
I just found this debate between the Rav and a Professor Greenberg. I have never watched it and I hope to find out just a little more than what I already know about the Kahanist ideal for a proud and strong Jewish identity.
