lubab: "...If he can get into Israel then all the other efforts will go much faster and better in the long run..."
Were Chaim allowed to make aliyah and given the political freedom to speak, write, and organize; I have no doubt that the vast majority of Israelis would agree with him and support him.
That being said, the problem Chaim faces is multi-faceted:
The Israeli government must first agree to allow Chaim's immigration and acquiring of Israeli citizenship.
The views of Rabbi Kahane are illegal in Israel, it is illegal in Israel to even harbor the ideas of Rabbi Kahane.
Unless and until the Israeli government allows freedom of thought, freedom of speech, and the freedom for Chaim to politically organize and legally run for elected office, Chaim's arriving in Israel will result in imprisonment without due process of law and/or worse.
In addition, the United States Department of State lists our late Rabbi Kahane and his political movement on their Official List of International Terrorist Organizations, so don't count on any support for Chaim coming from our own U.S. Federal Government.
According to the information coming from numerous media sources both here and abroad, the U.S. Government was in consultation with Benazhir Bhutto, and coordinating her "return from exile" to Pakistan to enable her to campaign for office in the 'hopes of restoring democracy'.
I am not so certain that I myself would want to be the recipient of such "assistance"; considering the outcome.
