This is probably, but not certainly, the year that sees the end to the United States’ three-decades-long effort to establish permanent American strategic bases in the Muslim Middle East and in Muslim Asia.

This effort began before the 9/11 attacks on New York and Washington in 2001. The attacks were revenge for Washington’s refusal to remove the airbase and troops it had installed in Saudi Arabia, the Holy Land of Islam, following the Persian Gulf War to liberate Kuwait, following Iraq’s invasion and occupation of that country.

America’s retaliation was the invasion of Afghanistan and destruction of its Taliban government, the invasion of Iraq and destruction of Saddam Hussein’s government and the country’s infrastructure. The Hussein government, dominated by Sunnis, was replaced with a puppet government dominated by Shiites. That government eventually turned against its occupiers and ordered them to leave — which they did. Today the country is assailed by violence as the Sunnis attempt to recover power. The U.S. has turned to wage its war on global terrorism elsewhere.

It turned to Syria, where it welcomed and supported a predominantly Sunni insurgency, which soon included and became dominated by al-Qaida militants and members of the group that chooses to call itself ISIS, the Islamic State of Iraq and Syria. Washington was dismayed because these people were also its enemies and Israel’s enemies. Iran and Hezbollah, together with Russia, were supporters of the Assad regime in Syria.

These jihadist forces, with allied Wahhabi and Salafist groups, were aided by Saudi Arabia — formerly America’s great ally and supplier of oil — and Qatar, a newer Sunni ally. The enemies of the Assad government were accustomed to get aid in wooden boxes stenciled “Gift of the American People.” No more; times had changed.

The Obama administration recently was eager — on Saudi Arabia’s and Israel’s urging — to bombard Damascus and the forces of Bashar Assad because of his alleged use of chemical weapons. To Washington’s good luck, Vladimir Putin and the Russian foreign office intervened to suggest that there was a better way to handle this. Now a chastened U.S. has been backing U.N. and Russian efforts to promote peace, thus far unsuccessfully.

When the American invasion of Iraq was being planned in 2002 and 2003, President George W. Bush had to have it explained to him that both Shiite and Sunni Muslim believers existed, had rival theological origins and beliefs and were power rivals. For Bush and millions of other Americans, they were all just Arabs. Thus the U.S. could be for and against Sunnis and Shiites according to what country is being talked about, and at what date on the calendar.

Accidents happen. The French-led intervention in Libya in 2011, belatedly joined by the U.S. and the North Atlantic Treaty Organization, overthrew President Moammar Gadhafi, but left his ample armories to be looted to serve internecine power struggles in Libya, and pushed the Mali mercenaries and various jihadist groups in the country southward into central Africa, and westward to Algeria, extending their power there and elsewhere in the Maghreb.

Texas Republican congressman Michael McCaul claimed last Sunday that “al-Qaida is spreading like a spider’s web — like a wildfire — throughout Northern Africa” posing a rising threat to the U.S. (Why a threat to the U.S. was not clear, but President Barack Obama, rather than Bush, was to blame.)

The immediate prospect on America’s other battleground, in Central Asia, is a disordered attempt to withdraw the U.S. army from Afghanistan, while continuing to deal with a nuclear Pakistan, which will be freed by America’s departure to pursue its own national interests, which are not those of the U.S. These chiefly concern Kashmir and Pakistan’s rival India, as well as who will prevail among the political forces of Afghanistan when the American-created government falls.

Among the questions yet unanswered are whether American forces now in Afghanistan will be able to withdraw intact, free from harassment; and what will happen to the CIA’s anti-Taliban CIA drone assassination program, now based in Afghanistan. According to the Los Angeles Times, the CIA is looking for a new Central Asian base, but no one knows any country — within drone range of Afghanistan and Pakistan’s northwestern territories, the main target area — eager to take in the CIA.

Another question follows: What would Pakistan’s reaction be absent America’s continuing program of assassination of Pakistan nationals, launched from the White House in Washington?

Indeed, why should the U.S. go on killing people in these countries when it no longer is at war in either Central Asia or the Middle East? Elements in the U.S. government seem determined to continue to make war against worldwide (Islamic?) radicalism, wherever it may exist. Others are not.

Despite what Americans want, people both in the Middle East and in Afghanistan now seem increasingly determined to take control of their own affairs, including their own wars, revolutions, dictators and military regimes. This seems wise.

The American departure will leave behind much carnage and ruin. It will leave America’s largest and most expensive (former) embassy on earth — “bigger than the Vatican City,” we proudly were told, as construction was under way in Baghdad’s Green Zone. It will serve as a monument to American strategic ambition, becoming the American Ozymandias (“look upon my works, ye Mighty, and despair!”). Tourists will visit it.
