In 1992, angry that Likud under prime minister Yitzhak Shamir bowed to US pressure and participated in the Madrid peace conference, Tehiya brought down his government. In so doing, it brought in Yitzhak Rabin and Shimon Peres and brought the country the Oslo process and Yasser Arafat in Ramallah.

In 1999, angry at Netanyahu for bowing to US pressure and agreeing to the Wye Plantation accords, the National Union brought down his government. In so doing, it brought in Ehud Barak and Yossi Beilin, the withdrawal from Lebanon and the Camp David summit.

In all, the total of Israelis who have been killed due to Oslo, the withdrawal from Lebanon and the Palestinian terror war which followed Camp David comes to around 2,000. The country's weakened position today in the US and Europe as well as in the Arab world, would have been inconceivable in 1992.

In both 1992 and 1999, the National Union and its predecessors were faced with two choices. They could remain ideologically pure by bringing down their own government and so risk empowering the Left, or they could recognize that governance is the art of compromise, keep a stiff upper lip and work from within the government to mitigate the strategic damage that in their view Shamir and Netanyahu caused by bowing to American pressure.

And in both cases, the National Union rejected its real choices in favor of an imaginary one. Both in 1992 and 1999 it chose to leave the government while pretending that there was no difference between Likud and Labor. By choosing this route, it effectively committed itself to strategic as well as political blindness since it was forced to claim - wrongly - that there was no difference between Madrid and Oslo or between Wye Plantation and Camp David.

Last Friday it was disclosed that on Wednesday afternoon, Netanyahu had reopened coalition talks with Kadima leader Tzipi Livni. Those talks had ended weeks ago after Livni demanded that Netanyahu agree to share the premiership with her through a rotation agreement, give her full control over strategy for dealing with the Palestinians and adopt the establishment of a Palestinian state as the primary goal of his government. All of Livni's demands were nonnegotiable and all of them, both separately and together, were unacceptable for Netanyahu. And so, he rejected them and for the past two and a half weeks has been concentrating his efforts on building a governing coalition with the right wing and religious parties.

Avigdor Lieberman's Israel Beiteinu with its 15 Knesset seats is set to be Likud's main coalition partner. Lieberman has been the most outspoken champion of a Likud-Kadima-Israel Beiteinu coalition. This makes sense from his perspective. Lieberman is viewed both by the West and by much of the country's leftist elite as a racist. Due both to his legal worries and to the fact that his actual policy preferences of surrendering the Galilee and the Negev to the Arabs are far left of center, Lieberman cares deeply about what the Left thinks of him. In his view, the only way to be accepted as legitimate in leftist circles is to compel Likud to move to the left by bringing Kadima into the government.

In part to satisfy Lieberman - without whom he cannot form a government - and in part because he remembers that it was the National Union which brought down his government 10 years ago, Netanyahu began his coalition building talks with Kadima. They collapsed only because Livni made demands that he could not meet.

In the current round of talks, Livni has reportedly maintained her demands, but now Netanyahu is reportedly accepting them - at least partially. The question that needs to be asked is what has changed in three weeks? Why has Netanyahu decided that Livni's previously unacceptable demands are now acceptable? The only reasonable answer is the National Union. Last week Katz scuttled negotiations with Likud because it refused his demand for the Construction and Housing Ministry. On Thursday, he joined hands with Habayit Hayehudi chairman MK Daniel Herschkowitz and announced that neither of the two parties would join Netanyahu's government if he doesn't meet all of their demands, including the Ministry of Education for Herschkowitz. Without the two parties, Netanyahu lacks a parliamentary majority.

It is possible that Katz and Herschkowitz are bluffing. In fact, it is likely that they are. But what their behavior shows clearly is that Netanyahu is correct when he says that a coalition that relies on them is inherently unstable. And so, he has moved back into Kadima's orbit.

If the Olmert-Livni-Barak government goes ahead with its plans to spring hundreds of mass murderers from prison in its last days in office, the threat they will unleash will just be added to the long list of serious threats that our strategically delusional leftist government has created and expanded during its tenure in office. It would be the height of irony - and tragedy - if due to the Right's proven political incompetence, the same political Left remains in power as the main partners in the Netanyahu government and so is given yet another opportunity to ruin the country.
