Is this much different from going on jihad?

The IDF, the organization he wants to join, is not a terrorist organization, tribesy.

Considering that you say that the group is banned as a terrorist group in Israel, would that not mean the IDF, if anything, would work against them?

Tribesman was talking about the Kahanist organisations, one of whose slogans "Kahane chai" was this chap's sig until someone complained. From wikipedia:

Following Kahane's death, no charismatic leader emerged to replace him, and Kahane's ideology declined in popularity among Israelis. However, two small Kahanist factions later emerged; one under the name of Kach and the other Kahane chai (Hebrew: כהנא חי, literally "Kahane lives [on]").

In 1994, following the killings in the Ibrahim Mosque by Kach supporter Dr. Baruch Goldstein, the Israeli government declared both parties to be terrorist organizations. The U.S. State Department also added Kach and Kahane Chai to its list of Foreign Terrorist Organizations. Providing funds or material support to these organizations is a crime in both Israel and the United States.

I suppose he's not as extreme as some I've seen, his dream being but to expel the Palestinians from the occupied territories. There were one or two (who were promptly banned) who argued that, since the original British mandate was Palestine-Transjordan, Greater Israel should include Jordan as well.
