MOST FUNDAMENTALLY, we see a growing assault on both the legitimacy and security of the State of Israel.

This assault comes from people who make clear they have no intention of ever living side-by-side in peace with a Jewish state - no matter how many concessions Israel might make. The reason for this is also clear: These are men who cannot abide the idea of freedom, tolerance and democracy. They hate Israel for the same reasons they hate us.

As I speak, the flashpoint is Gaza. For months now, Hamas has been raining down rockets on Israeli civilians. Like all terrorist attacks, the aim is to spread fear within free societies, and to paralyze its leaders. This Israel cannot afford. I do not need to tell anyone in this room that no sovereign nation can sit by while its civilian population is attacked.

Hamas knows this better than we do. And Hamas understands something else as well: In the 21st century, when democratic states respond to terrorist attacks, they face two terrible handicaps.

THE FIRST HANDICAP is military. It's true that Israel's conventional superiority means it could flatten Gaza if it wanted. But the Israel Defense Forces - unlike Hamas - are accountable to a democratically chosen government.

No matter which party is in the majority, every Israeli government knows it will be held accountable by its people and by the world for the lives that are lost because of its decisions. That's true for lives of innocent Palestinians caught in the crossfire. And it's also true for the Israeli soldiers who may lose their lives defending their people.

In this kind of war, Hamas does not need to defeat Israel militarily to win a big victory. In fact, Hamas knows that in some ways, dead Palestinians serve its purposes even better than dead Israelis.

In the West we look at this and say, "It makes no sense." But it does make sense.

If you are committed to Israel's destruction, and if you believe that dead Palestinians help you score a propaganda victory, you do things like launch rockets from a Palestinian schoolyard. This ensures that when the Israelis do respond, it will likely lead to the death of an innocent Palestinian - no matter how many precautions Israeli soldiers take.

Hamas gets away with this, moreover, because it does not rule Gaza by the consent of those it claims to represent. It rules by fear and intimidation. It is accountable to no one but itself.

This is the chilling logic of Gaza. And it helps explain why even a strong military power like Israel can find itself at a disadvantage on the ground.

THE SECOND HANDICAP for Israel is the global media war. For Hamas, the images of Palestinian suffering - of people losing their homes, of parents mourning their dead children, of tanks rolling through the streets - create sympathy for its cause.

In a battle marked by street to street fighting, the death of innocents is all but inevitable. That is also true of Gaza. And these deaths have led some to call for Israel to be charged with war crimes by an international tribunal.

But I am curious: Why do we never hear calls for Hamas leaders to be charged with war crimes?

Why, for example, do we hear no calls for human rights investigations into Hamas gunmen using Palestinian children as human shields? Why so few stories on the reports of Hamas assassins going to hospitals to hunt down their fellow Palestinians? And where are the international human rights groups demanding that Hamas stop blurring the most fundamental line in warfare: the distinction between civilian and combatant?

I suspect the answer has to do with the same grim logic that leads Hamas to provoke a military battle it knows it cannot win. Whether Israel is ever found guilty of any war crime hardly matters. Hamas gets a propaganda win simply by having the charge made often and loudly enough.

In this, Israel finds itself in much the same position the United States found itself in Iraq before the surge. There, al-Qaida realized that it was in its interests to provoke sectarian violence between Shia and Sunni - no matter what the cost to innocent Iraqis. That is the nature of terror. And what we are seeing in Gaza is just one front in this much larger war.

IN THE WEST, we are used to thinking that Israel cannot survive without the help of Europe and the United States. Tonight I say to you: Maybe we should start wondering whether we in Europe and the United States can survive if we allow the terrorists to succeed in Israel.

In this new century, the "West" is no longer a matter of geography. The West is defined by societies committed to freedom and democracy. That at least is how the terrorists see it. And if we are serious about meeting this challenge, we would expand the only military alliance committed to the defense of the West to include those on the front lines of this war. That means bringing countries such as Israel into NATO.

My friends, I do not pretend to have all the answers to Gaza this evening. But I do know this: The free world makes a terrible mistake if we deceive ourselves into thinking this is not our fight.
In the end, the Israeli people are fighting the same enemy we are: cold-blooded killers who reject peace, who reject freedom and who rule by the suicide vest, the car bomb and the human shield.

Against such an enemy, I will not second-guess the decisions of a free Israel defending her citizens. And I would ask all those who support peace and freedom to do the same.
