For leaders in democracies, perhaps the most difficult decision is to change course. Decision-making is hard enough. Revisiting decisions and acknowledging mistakes is simply beyond the capabilities of most leaders. Once they have chosen a strategy, they stick with it for better or for worse.

For a leader to change strategic course, he must first be convinced that his own fortunes are inextricably linked with maintaining failure or moving on towards success. He must believe, in other words, that he has no choice other than to change course.

The current issue of the Weekly Standard contains two articles which lay bare this basic truth. In one, "How Bush decided on the surge," Fred Barnes describes how US President George W. Bush decided to adopt a new strategy for winning the campaign in Iraq. In the other, "Ehud Olmert's Israel," Peter Berkowitz describes how Prime Minister Ehud Olmert has refused to revisit his own strategies for contending with the burgeoning threats to Israel's national security.

Barnes's article depicts a president who at the end of 2006 found himself isolated from the military, Congress and his own Secretary of State as the campaign in Iraq appeared increasingly unwinnable. The going consensus asserted that the reason the war was unwinnable was because US forces themselves were the cause of the fighting. If the US left, or simply hid in big bases outside the population centers and sufficed with training Iraqi forces, then the war would end.

Bush didn't believe them. And he couldn't accept the view that victory was unattainable. As he put it to Barnes, "Failure was no option…. I never thought I had to give up the goal of winning." So he didn't. Instead, working with his National Security Council and relying on the work of people outside the administration and the Pentagon, he embraced the view that the war was the fault of the terrorists - not the US. Bush recognized that far from wishing for the US forces to withdraw from the country, the Iraqis wished for the Americans to stay and protect them. The surge strategy - which involved an increase in forces, and an intimate engagement of the forces in securing the lives and property of Iraqi civilians - has done just that. And the results have been dramatic.

As Max Boot reported in the Weekly Standard, "Iraqi and American deaths fell by approximately 80 percent between December 2006 and December 2007, and life is returning to a semblance of normality in much of Baghdad." Wherever the Americans are operating, al-Qaida is being defeated, the Shi'ite militias are fading away and life is changing for the better as more and more Iraqis come to trust and support the Americans and the Iraqi security forces working with them.

WITH THE presidential race moving into full swing, the sustainability of Bush's new strategy into the next administration is a key concern. The media's coverage of the campaign in Iraq has been so negative for so long that in spite of the transformation of the security situation in the country over the past year, the public still considers the war to have been a failed endeavor. More Americans trust the Democrats, who have pledged to withdraw from Iraq, to handle the war than Republicans, who have pledged to see it through to victory.

On the other hand, in spite of the media's condemnation of the war, Americans today believe they are winning the war in Iraq. According to an NBC News - Wall Street Journal poll, 39 percent of Americans believe that the situation in Iraq has improved over the last six months and only 16 percent believe it has gotten worse. Even if the Democrats win the White House in November, it is hard to see the next president convincing the American people to turn their backs on victory.

Barnes is impressed by Bush's courage to move forward, almost alone and change the war-fighting strategy in order to enable victory in Iraq. If Bush hadn't acted as he did when he did, there can be little doubt that the US would have lost in Iraq. The public was willing to accept defeat. Congress was positively demanding defeat. The New York Times might have even granted Bush 15 minutes of sympathetic coverage if he had behaved "pragmatically" and embraced defeat in Iraq.

THE FACT that a failed leader can expect to find public support for his weakness was manifested in Berkowitz's portrait of Olmert. Just as the media has manufactured false realities to convince some 60 percent of the American public that the Iraq campaign is not only unwinnable but that the US doesn't deserve to win, so too, the media has labored for years to convince the majority of Israelis that we cannot win and indeed have no right to victory.

Berkowitz's opening paragraph attests to the success of their labors. He began his profile of Olmert by noting that some 70 percent of Israelis support the establishment of a Palestinian state. He asserted, as the media does, that the only people in Israel who don't support the establishment of such a state are right-wing extremists who no one would want to be associated with.

Having established that the only socially and morally acceptable view of Israel's conflict with the Palestinians is that Israel must feel bad for controlling Judea, Samaria and united Jerusalem, and that Israelis must happy that Israel no longer controls Gaza, Berkowitz goes on to uphold Olmert as a competent and socially acceptable leader.

This is the same Ehud Olmert who led Israel to defeat in the 2006 war in Lebanon. The same Olmert who has exhibited unconscionable incompetence in contending with the Hamas caliphate in Gaza, its rocket and mortar war against southern Israel and its takeover of Gaza's international border with Egypt. And this is the same Olmert who now fervently advocates surrendering Judea, Samaria and parts of Jerusalem to Fatah leader Mahmoud Abbas. Such a land handover would place all of Israel within Palestinian and Lebanese rocket, mortar and missile range. Moreover, Olmert has done nothing to stem the Bush administration's abandonment of Israel as a strategic ally and has been so feckless in his handling of Iran's nuclear weapons program that Israel finds itself completely alone to face Iran as the mullahs surge toward nuclear capabilities.
