While world attention is focused on Aleppo and when Bashar Assad might fall, Syria itself may be about to disintegrate.

“Apart from political maps of mankind, there are natural maps of mankind. … One of the first laws of political stability is to draw your political boundaries along the lines of the natural map of mankind.”

So wrote H.G. Wells in “What Is Coming: A Forecast of Things to Come After the War” in the year of Verdun and the Somme Offensive.

In redrawing the map of Europe, however, the statesmen of Versailles ignored Wells and parceled out Austrians, Hungarians, Germans and other nationalities to alien lands to divide, punish and weaken the defeated peoples.

So doing they set the table for a second world war.

The Middle East was sliced up along lines set down in the secret Sykes-Picot agreement. But with the Islamic awakening and Arab Spring toppling regimes, the natural map of the Middle East seems now to be asserting itself.

Sunni and Shia align with Sunni and Shia, as Protestants and Catholics did in 17th-century Europe. Ethiopia and Sudan split. Mali and Nigeria may be next. While world attention is focused on Aleppo and when Bashar Assad might fall, Syria itself may be about to disintegrate.

In Syria’s northeast, a Kurdish minority of 2 to 3 million with ethnic ties to Iraqi Kurdistan and 15 million Kurds in Turkey seems to be dissolving its ties to Damascus. A Kurdish nation carved out of Syria, Iraq, Turkey and Iran would appear to be a casus belli for all four nations. Yet in any natural map of the world, there would be a Kurdistan.

The Sunni four-fifths of the Syrian population seems fated to rise and the Muslim Brotherhood to rule, as happened in Egypt. The fall of Assad and his Shia Alawite minority would be celebrated by the Sunni across the border in Iraq’s Anbar province, who would then have a powerful new ally in any campaign to recapture Sunni lands lost to Iraqi Shia.

With its recent murderous attacks inside Iraq, al-Qaida seems to be instigating a new Sunni-Shia war to tear Iraq apart.

The fall of the Alawites in Damascus would end the dream of a Shia crescent — Iran, Iraq, Syria and Hezbollah — leave Hezbollah isolated, and conceivably lead to a renewal of Lebanon’s sectarian and civil war.

The losers in all this? Certainly Iran, which seems fated to lose its only Arab ally, Syria, and its land link to Hezbollah.

That would make Israel a winner. But Israel’s situation appears more perilous than it was a decade ago.

In Egypt, the Muslim Brotherhood has replaced Hosni Mubarak, who kept the peace in Sinai and the lid on Hamas. Recently, new Egyptian President Mohamed Mursi met with Hamas’ Khaled Meshaal at the presidential palace in Cairo. The Sinai is becoming a no man’s land where terrorists plot and Africans cross to Israel.

To Israel’s east, there is no true peace with the Palestinians, and the Jordanian throne has rarely been shakier. On the Golan Heights, quiet for decades, the future may see Syrian troops loyal to a militant Sunni regime in Damascus. Hezbollah sits on Israel’s northern border. Beyond is a Turkey no longer friendly.

Israel is blaming the atrocity in Bulgaria, in which Israeli tourists were massacred, on Iran. But neither the Bulgarians nor the Americans appear to know who did it. And why would the Iranians, who, following the slaughter, publicly denounced such atrocities against civilians, do it?

Were an Iranian hand to be found in this act of barbarism, it would give Israel justification for an attack, igniting a war in which America could be dragged in.

Why would Iran want a war with the United States when that would mean destruction of its air force, navy, missile force and nuclear program, a crippling blockade and perhaps destruction of its vital oil facilities on Kharg Island?

Whoever was behind the attack on the Israeli tourists seems to want a war between the Jewish state of Israel and the Shia state of Iran.

Who would benefit from such a war?

Answer: Al-Qaida, which, during the Iraq War, urged the United States to bomb Iran back to the Stone Age. An al-Qaida affiliate has also attacked Israeli vacationers before, at Egyptian resorts on the Gulf of Aqaba.

“There is an international plot against Gulf states in particular and Arab countries in general … to take over our fortunes,” says Dubai’s chief of police. “I had no idea that there is this large number of Muslim Brotherhood in the Gulf states.”

What is al-Qaida’s goal? Ignite Sunni-Shia wars and Muslim-Christian clashes in Arab states. Draw in the Americans to smash Iran. And when the Sunni are ascendant, expel the Americans and Christians, isolate Israel and set about creating the caliphate of Osama bin Laden’s dream.

If a U.S. war on Iran is good for al-Qaida, how can it be good or us?
