On the darker upper strip of my computer screen I saw my eyebrows rising, as I read, for the first time, President Obama’s mission in Iraq and Syria. Now, as his aides and spokespersons drone on and on about that mission, I get ticked off or, alternately, amused.

Can the United States and its allies really “degrade and ultimately destroy” the Islamic State in Iraq and Syria (ISIS or ISIL)?

Personally, I deplore this war because of the deaths and devastation it’s going to cause, and the piles of dough we, American taxpayers, are squandering on it. So far the war’s price tag is estimated to be $1 billion a month. It’s likely to rise.

Yet I also see the war having a far-reaching, liberating effect on Arab societies. I see it reviving and strengthening the Arab Spring, which Arab monarchies and dictatorships had foolishly thought they had behind them. More on this in a minute.

Meanwhile, I’m afraid Obama isn’t going to “destroy” ISIS. Remember his repeated vows to “disrupt, dismantle and defeat” Al Qaeda during the Afghanistan war? Thanks mainly to that war, Al Qaeda and its many affiliates have mushroomed in the Middle East, North and West Africa, and elsewhere. If Afghanistan, Iraq and Vietnam had any lesson for the United States, it’s that conventional military establishments, however powerful, can’t defeat modern guerrilla forces that are ready to die to end their oppression and avenge their subjugation and humiliation.

Afghan Mujahedeen taught this lesson to the Soviet Union in the 1980s, then the world’s largest conventional military juggernaut. The Lebanese Hezbollah and Palestinian guerrilla groups in Gaza have driven it home to Israel, the superpower in Middle East.

Ignoring these glaring lessons and lurching into a new war in the hope of stamping out the world’s most powerful Muslim guerrilla force is just insane. Albert Einstein defined “insanity” as “doing the same thing over and over again, but expecting different results.”

The gruesome atrocities that ISIS has committed against civilians in Iraq and Syria are indeed heinous and inhuman. They’re repugnant to Islamic tenets and principles. Beheading innocent civilians, killing Yazidis and Christians or converting them to Islam by force are certainly not part of the “jihad,” struggle authorized by Islam, they claim to have waged.

Islam sanctions two kinds of jihad. The greater jihad,  jihad al-kabir, is the struggle to resist one’s own immoral impulses and actions. The lesser jihad,  jihad al-saghir, is armed struggle to defend one’s community or territory against outside aggression. ISIS obviously has proclaimed the lesser jihad against the Shiite government and militias in Iraq, the Alawite government in Syria as well as America and its allies. Islam would probably support its armed struggle if it is, or was, meant to resist the U.S.-led invasion of Iraq, Shiite pogrom against Sunni Arabs in Iraq or the suppression and oppression of people by the Bashar al-Assad government in Syria.

But Islamic law strongly prohibits its inhuman atrocities against civilians, mentioned above. These crimes belong to the categories of the brutal torture, murder and humiliation of mostly innocent Muslims in Abu Gharib, Guantanamo Bay, and elsewhere by American forces. They’re as barbaric as American soldiers peeing on Afghan Muslim corpses, or Israelis slaughtering Gazan children.

In any case, the more America and its allies beat up on ISIS, the more it will attract recruits and monetary support from fellow Sunnis from around the world. Already, some 3,000 American and European Sunni youths and many thousands more from the Muslim world have joined the guerrilla organization. I expect the trend to accelerate in the months and years ahead.

It reminds me of a comment an Iraqi friend made to me during one of my three research trips to Iraq. In 1991 Subhy Haddad, a veteran Iraqi journalist, was working for the Japanese newspaper Asahi Shimbun. I had him over for lunch at Baghdad’s Sagman Hotel, where I was staying.

Between bites on his eggplant Domla – eggplant with meat, vegetables and spices stuffing – Haddad said I wouldn’t be able to interview some of the Shiite intellectuals and politicians I had on a list. About half of them had fled to Shiite Iran to escape then Sunni Arab President Saddam Hussein’s persecution. If Sunni Arabs (as different from Sunni Kurds) ever got knocked out of power, he continued, Shiites would wreak vengeance on them. Iraq’s Sunni Arabs “would then turn to their fellow Sunnis in the region” for support. Iraqis, he added, were “more loyal to their ethnic groups than to Iraq.”

I remembered Haddad when successive Shiite governments in Baghdad and their brutal militias began slaughtering Sunni Arabs after the United States had overthrown the Saddam regime. Many of those persecuted Sunni Arabs joined Al Qaeda in Iraq to resist the U.S. invasion and the Shiite pogrom. ISIS has resumed that struggle and strengthened it manifold.

That the United States sired ISIS is missing from American discourse on that militant group. Senator Carl Levin was a rare exception. “ISIS did not exist before our invasion of Iraq,” said the chairman of the Senate Arms Services Committee at a hearing on the issue. “They are a consequence of our invasion of Iraq.”

Levin echoed a chorus of voices from politicians and pundits in the Middle East. ISIS is “the product of foreign invasion,” Iranian Foreign Minister Javad Zarif told the Council on Foreign Relations in New York.

And America’s expedition against ISIS is going to produce the same results as did its war against Al Qaeda in Afghanistan: spread and bolster the movement, aggravating threats to American security.

If the Sunni Arab militancy in Iraq and Syria has alarmed the United States, it has spawned panic among Arab monarchies, which are its next targets. In fact ISIS, the Al Qaeda offshoot Jabhat al-Nusra and other Islamist militant groups already are calling for the ouster of repressive Arab monarchies. No wonder five of those monarchies – Saudi Arabia, Bahrain, Qatar, Jordan and the United Arab Emirates – have jumped on America’s anti-ISIS bandwagon in a desperate effort to save their thrones.

The thousands of Arab youths from Persian Gulf countries who are honing their fighting skills in this war will one day return home. They will almost inevitably revive and fire up the simmering revolutionary movements against their tyrannical monarchies, the most formidable they ever faced.

I don’t expect many of these anachronistic power structures to survive another Arab generation.
