".....These tactical achievements are part of a larger picture, however, and that picture is not a pretty one. Israel has also lost several wars in the past -- none of them decisively, of course -- and its ability to use force to achieve larger strategic objectives has declined significantly over time. This is why Israelis frequently speak of the need to restore their "deterrent"; they are aware that occasional tactical successes have not led to long-term improvements in their overall security situation. The assault on Gaza is merely the latest illustration of this worrisome tendency.
What does the record show?.....
The moral of this story is that there is no reason to think that Israel always has well-conceived strategies for dealing with the problems that it faces. In fact, Israel's strategic judgment seems to have declined steadily since the 1970s -- beginning with the 1982 invasion of Lebanon -- perhaps because unconditional U.S. support has helped insulate Israel from some of the costs of its actions and made it easier for Israel to indulge strategic illusions and ideological pipe-dreams. Given this reality, there is no reason for Israel's friends -- both Jewish and gentile -- to remain silent when it decides to pursue a foolish policy. And given that our "special relationship" with Israel means that the United States is invariably associated with Jerusalem's actions, Americans should not hesitate to raise their voices to criticize Israel when it is acting in ways that are not in the U.S. national interest.
Those who refuse to criticize Israel even when it acts foolishly surely think they are helping the Jewish state. They are wrong. In fact, they are false friends, because their silence, or worse, their cheerleading, merely encourages Israel to continue potentially disastrous courses of action. Israel could use some honest advice these days, and it would make eminently good sense if its closest ally were able to provide it. Ideally, this advice would come from the president, the secretary of state, and prominent members of Congress -- speaking as openly as some politicians in other democracies do. But that's unlikely to happen, because Israel's supporters make it almost impossible for Washington to do anything but reflexively back Israel's actions, whether they make sense or not. And they often do not these days."
