Given America’s poor record in winning wars over the past seven decades and other foreign policy blunders that do not distinguish between Democratic and Republican administrations, last week’s column argued that a major cause had to be a missing or flawed gene in the nation’s strategic DNA. There is, however, another factor. That factor is American strategic amnesia. Strategic amnesia is not limited to one state or government. Hitler forgot Napoleon’s misbegotten sortie into Russia. Alexander’s Greece, Mongols, Brits, Russians and Americans, among others, likewise, fell into Afghan’s graveyard of empires. And as the US and other countries are extricating citizens and Afghans who face Taliban wrath and reprisals, this amnesia applies to a crucial element of conflict. In most militaries, young officers are taught that among the most difficult and dangerous manoeuvres is withdrawing or retreating under fire. The question of how the last American forces will depart Kabul’s Karzai International Airport is crucial, should the Taliban change their minds and oppose any extrication or a sea of Afghans make takeoffs and landings virtually impossible by blocking the sole runway or aircraft movement on the ground. Complicating these problems is the ancient military law that if anything conceivably could go wrong, it will. And that applies more broadly as the fiasco of responding to Hurricane Katrina in 2005 tragically demonstrated. Too many examples of this axiom do double duty in littering history and contributing to strategic amnesia. Perhaps, the most egregious for Americans of a certain age was the failed hostage rescue attempt to Tehran in April 1980 called Eagle Claw. And even the raid that killed Osama bin Laden in May 2011 in Abbottabad, Pakistan came within inches of failing. The assault on the bin Laden compound – deemed a great success – was almost lost. In November 1979, so-called Iranian students stormed and occupied the US embassy in Tehran for a second time; seizing 52 American hostages. That prior February, the embassy had been taken over and then returned. The Carter administration began planning for a mission to free the hostages that became known as Desert One. Eight RHD-53 helicopters were to lift off the aircraft carrier USS Nimitz in the Persian Gulf and fly about 400 miles to a rendezvous site in Iran called Desert One. There, the helos would be met by three EC-130’s carrying 119 special forces with three more re-fuelers. After refuelling and embarking the soldiers, the helos were to fly to Desert Two outside Tehran, spend the night and the next day, launch the mission to free the hostages in the embassy and two held at the Foreign Ministry. The ground force with the hostages would then drive in buses to a nearby landing strip where C-141 transports would fly everyone to safety. Given the complicated and questionable planning, the likelihood that something would go wrong was altogether too likely. A sandstorm that hindered the helicopters initial ingress was the first of what would prove to be catastrophic events. The specially fitted RHD-53’s had never been flown by their marine pilots before having just been received aboard Nimitz. Ordered to fly at low levels to avoid radar detection in a sand storm was nearly mission impossible. One helo malfunctioned and turned back. A second was forced to land. And a third arrived at Desert One with cracked rotor blades making it unsafe to fly. Down to five when a minimum of six helos was required, the mission was aborted. However, by bad luck, a busload of tourists was driving through Desert One and were captured. Then a truck presumably used by smugglers was detected and destroyed by a US rocket illuminating the landing zone. Last and tragically, one of the helos collided with a C-130 on the ground causing an explosion killing eight; ending a nightmare of what could go wrong. But even the assault on the bin Laden compound – deemed a great success – was almost lost. Attempting to land on the compound grounds, an unexpected backdraft from the rotor blades caused the helo to crash. Fortunately, the pilot was both skilled and lucky and major injuries were avoided. The mission succeeded – just. As the US forgot the unhappy history of prior invasions of Afghanistan in planning for the withdrawal of its soldiers and marines from Karzai Airport, lessons from these very complex and dangerous military operations must not be lost. If the Taliban cooperate, terrorists do not strike and fleeing Afghans do not halt flights, all could work. But that entails a lot of buts.
