Why does Mao Zedong, who murdered 10 times as many Chinese as Japan in World War II, lie in honor in a crystal sarcophagus in Tiananmen Square? Because Mao is still seen to have ‘liberated” China from a century of rule by hated Japanese and Western imperial powers and their lackeys.

Why was Saigon renamed for Ho Chi Minh? Why do his remains rest in honor in Hanoi? Because “Uncle Ho” is seen by his people as having driven out the Japanese, French and Americans, and united all Vietnamese in a national home.

Even Fidel Castro, who brought the most successful country in Latin America down close to the level of Haiti, still has admirers inside and outside Cuba. Why? Because he defied the “Yanquis” and threw them out, along with their quisling Fulgencio Batista.

Like Mao, Ho and Castro, Osama tapped into the most powerful current of the age: ethnic nationalism, the desire of peoples to be rid of foreign rule and any oppressive foreign presence, and to put up against a wall all indigenous traitors who do the foreigners’ will.

Lest we forget, Osama was once an ally of Ronald Reagan’s America. We provided the Stingers, and he provided the money for the Afghan mujahedeen to administer the deathblow to the Soviet Empire.

Some yet argue that Osama and al-Qaida attacked us because they hate our freedoms. Why, then, did they fight the Russians? Did they hate the freedoms enjoyed by Soviet citizens in Leonid Brezhnev’s time?

In his 1998 declaration of war, Osama gave three reasons. Americans, he said, had deployed their infidel troops on sacred Saudi soil. Americans were strangling a crushed Iraqi people with murderous sanctions. Americans were enabling Zionists to oppress and rob Palestinian Arabs of their lands.

Osama plugged his personal war into the anti-American currents running in the region. It was whom he was fighting against, us, not the new caliphate he claimed to be fighting for, a utopian absurdity, that caused scores of millions to admire him, even if many were horrified by his methods.

It was when al-Qaida took to killing Arabs and Muslims that Osama lost the prestige he once had.

Osama is dead and gone. But the ideas he tapped into—the desire of Arab peoples to break free, to reclaim their sovereignty, to restore their past greatness, to be rid of the foreigner and his lackeys—are also the motivating ideas of the Arab Spring.

And as Victor Hugo reminded us, “Greater than the tread of mighty armies is an idea whose time has come.”
