Not that anyone in a position of power seems to notice, but there’s a simple rule for American military involvement in the Greater Middle East: once the U.S. gets in, no matter the country, it never truly gets out again. Let’s start with Afghanistan. The U.S. first entered the fray there in 1979 via a massive CIA-led proxy war against the Soviets that lasted until the Red Army limped home in 1989. Washington then took more than a decade off until some of the extremists it had once supported launched the 9/11 attacks, after which the U.S. military took on the role abandoned by the Red Army and we all know where that’s ended -- or rather not ended almost 16 years later. In the “longest war” in American history, the Pentagon, recently given a free hand by President Trump, is reportedly planning a new mini-surge of nearly 4,000 U.S. military personnel into that country to “break the stalemate” there. Ever more air strikes and money will be part of the package. All told, we’re talking about a quarter-century of American war in Afghanistan that shows no sign of letting up (or of success). It may not yet be a “hundred-years’ war,” but the years are certainly piling up.

Then, of course, there’s Iraq where you could start counting the years as early as 1982, when President Ronald Reagan’s administration began giving autocrat Saddam Hussein's military support in his war against Iran. You could also start with the first Gulf War of 1990-1991 when, on the orders of President George H.W. Bush, the U.S. military triumphantly drove Saddam’s army out of Kuwait. Years of desultory air strikes, sanctions, and other war-like acts ended in George W. Bush’s sweeping invasion and occupation of Iraq in the spring of 2003, a disaster of the first order. It punched a hole in the oil heartlands of the Middle East and started us down the path to, among other things, ISIS and so to Iraq War 3.0 (or perhaps 4.0), which began as an air campaign in August 2014 and has yet to end. In the process, Syria was pulled into the mix and U.S. efforts there are still ratcheting up almost two years later. In the case of Iraq, we’re minimally talking about almost three decades of intermittent warfare, still ongoing.

And then, of course, there’s Somalia. You remember the Blackhawk Down incident in 1993, don't you? That was a lesson for the ages, right? Well, in 2017, the Trump administration is sending more advisers and trainers to that land (and the U.S. military has recently suffered its first combat death there since 1993). U.S. military activities, including drone strikes, are visibly revving up at the moment. And don’t forget Libya, where the Obama administration (along with NATO) intervened in 2011 to overthrow autocrat Muammar Gaddafi and where the U.S. military is still involved more than six years later.

Last but hardly least is Yemen. The first U.S. special ops and CIA personnel moved into a “counter-terrorism camp” there in late 2001, part of a $400 million deal with the government of then-strongman Ali Abdullah Saleh, and the CIA conducted its very first drone assassination in that country in November 2002. Almost 16 years later, as Pentagon expert Bill Hartung reports in “Destabilizing the Middle East (Yet More),” the U.S. is supporting a grim Saudi air and ground war of terror there, while its own drone strikes have risen to new highs.

It’s a remarkable record and one to keep in mind as you consider Hartung’s account of President Trump’s fervent decision to back the Saudis in a big league way not just in their disastrous Yemeni war, but in their increasingly bitter campaign against regional rival Iran. After so many decades of nearly unending conflict leading only to more of the same and greater chaos, you might wonder whether an alarm bell will ever go off in Washington when it comes to the U.S. military and war in the Greater Middle East -- or is Iran next?
