Sounds to me like the Israeli Parliament has it's own share of "extremists" in the ruling party.
Here are portions of the Likud Party platform:

Declaration of a State
A unilateral Palestinian declaration of the establishment of a Palestinian state will constitute a fundamental and substantive violation of the agreements with the State of Israel and the scuttling of the Oslo and Wye accords. The government will adopt immediate stringent measures in the event of such a declaration.
Settlements
The Jewish communities in Judea, Samaria and Gaza are the realization of Zionist values. Settlement of the land is a clear expression of the unassailable right of the Jewish people to the Land of Israel and constitutes an important asset in the defense of the vital interests of the State of Israel. The Likud will continue to strengthen and develop these communities and will prevent their uprooting.
The Partition of the Negev
Israel rejects out of hand ideas raised by Labor Party leaders concerning the relinquishment of parts of the Negev to the Palestinians. The practical meaning of this plan is that the "Green Line" should no longer be viewed as a "Red Line", which draws us closer to the partition plan of 1947 as it opens the door to the principle that the fate of the Galilee, the Triangle and additional areas within Israel is negotiable. The Likud asserts that such proposals by the Labor Party leadership may literally cause the dismemberment of the State of Israel.
The Permanent Status
The overall objectives for the final status with the Palestinians are: to end the conflict between Israel and the Palestinians on the basis of a stable, sustainable agreement and replace confrontation with cooperation and good neighborliness, while safeguarding Israel's vital interests as a secure and prosperous Zionist and Jewish state.
The Likud government will honor all the international agreements signed by its predecessors and strive to achieve a final status arrangement with the Palestinians. The only way to reach a final status arrangement is via dialogue and political negotiations.
The permanent status arrangement will minimize the security dangers implicit in the Oslo accords. The primary such danger is the presence and the possible expansion of the Palestinian security forces within close range of Israel's population centers, government offices, emergency warehouses and staging areas of the Israel Defense Forces.
The permanent status arrangement shall be based on the following principles:
Self-Rule
The Government of Israel flatly rejects the establishment of a Palestinian Arab state west of the Jordan river.
The Palestinians can run their lives freely in the framework of self-rule, but not as an independent and sovereign state. Thus, for example, in matters of foreign affairs, security, immigration and ecology, their activity shall be limited in accordance with imperatives of Israel's existence, security and national needs.
Jerusalem
Jerusalem is the eternal, united capital of the State of Israel and only of Israel. The government will flatly reject Palestinian proposals to divide Jerusalem, including the plan to divide the city presented to the Knesset by the Arab factions and supported by many members of Labor and Meretz. The government firmly rejects attempts of various sources in the world, some anti-Semitic in origin, to question Jerusalem's status as Israel's capital, and the 3,000-year-old special connection between the Jewish people and its capital. To ensure this, the government will continue the firm policies it has adopted until now:
No diplomatic activity will be permitted at Orient House. The government stopped the stream of visits by heads of state and ministers at Orient House, begun under the left-wing government.
The presence of the Israeli police in eastern Jerusalem will be increased. This in addition to the new police posts and reinforcements in the neighborhoods.
The Likud government will act with vigor to continue Jewish habitation and strengthen Israeli sovereignty in the eastern parts of the city, while emphasizing improvements in the welfare and security of the Arab residents. Despite protests from the left, the Likud government consistently approved the continuation of Jewish living within the Old City and in 'City of David'.
