This week the United Nation's Human Rights Council produced a 600-page report alleging that Israel carried out war crimes in Gaza. The Goldstone Report—named for its chief investigator Richard Goldstone—also asserts that Israel's motives for its operation against Hamas nine months ago were purely political. I am outraged by these accusations. Let me explain why.

It is the duty of every nation to defend itself. This is a basic obligation that all responsible governments owe their citizens. Israel is no different.

After enduring eight years of ongoing rocket fire—in which 12,000 missiles were launched against our cities, and after all diplomatic efforts to stop this barrage failed—it was my duty as defense minister to do something about it. It's as simple and self-evident as the right to self-defense.

While such logic eluded Mr. Goldstone and his team, it was crystal clear to the thousands of Israeli children living in southern Israel who had to study, play, eat and sleep while being preoccupied about the distance to the nearest bomb shelter. When I accompanied then-presidential candidate Barack Obama on his visit to the shelled city of Sderot, he said "If somebody was sending rockets into my house where my two daughters sleep at night, I'm going to do everything in my power to stop that. And I would expect Israelis to do the same thing." Too bad the Human Rights Council wasn't listening.

Whenever we are forced to defend our own lives, it is our obligation to do so in a way that ensures that the lives of innocent civilians on the other side are protected. This duty becomes extremely difficult when we have to face an enemy that intentionally deploys its forces in densely populated areas, stores its explosives in private homes, and launches rockets from crowded school yards and mosques. In Gaza, we reached out to the civilians via millions of leaflets, telephone calls and text messages urging them to leave areas before we acted.
