Thanks,
Danny, what did Chaim say?
from what i recall, he said that he agreed on a ton of things that Rabbi kahane believed..but not 100% of things..i dont' remember that much more...
Depends what you mean by 'ideology'.
The ideology at play here is really 'Kahanism'.
If Yisrael wants to know the political differences the two held, two quick examples come to mind.
On America: Rabbi Kahane was an activist in support of the Vietnam War. He felt that both America and Israel's fate was somehow tied to the going's on in South Asia. Although Chaim was too young to be an activist at this time, Chaim has stated that this is a point where they would have differed.
On Israel: Chaim began a campaign to stop the Camp David Accords between Egypt and Israel in the late 1970's. Rabbi Kahane advised Chaim to direct his energy elsewhere. Rabbi Kahane obviously opposed the accords, but did not believe it was productive to fight them and risk going to jail while the larger issue of Soviet Jewry stood unresolved. Chaim has mentioned that in retrospect the Rav was correct.
