It's a Torah book soo it is obvious why Barnes and Nobles wouldn't have it (I wouldn't expect a major store to have it). Some Jewish bookstores do have Rav Kahane's books. If they dont have it inside, you can ask and they might make an order (as with other books also). It's all supply and demand. Unfortunatly though I dont believe that their is a big enough supply for these books. Maybe with a better advertisement things will change.
Warning it is a Torah book, suitable more for a Jew who has accepted the Torah as Emet. (It's not as political as the other secular oriented books of his), but it is brilliant, and I highly recommend the books for Jews.
less demand in the diaspora, because the most serious jewish zionists are in israel..
apparently his name is written on many walls, my friend had seen it. I didn't see it when I was with him, prob 'cos it had been rubbed off by the govt.
In jerusalem there was a huge jewish bookstore , I saw "the wit and wisdom of rabbi meir kahane" there..
It's interesting the religious similarity between he and rabbi yissachar shlomo teichtal. Rabbi teichtal was an adult during the holocaust, witnessing it rather helpless, he was in eastern europe. Rabbi Kahane was in america, only 10 years old. He couldn't do anything. Later he spoke about what should have happened, jews should have sat on the white house lawn singing "that well known jewish hymn" "no no we don't go!!!!!!".. (kahane speech in skokie)
The bookshop had rabbi teichtal's book a few shelves above his.
Rabbi Kahane was very multi-facted, nobody compares to him.
