Everybody in the Afghan national army already knows that the war is lost. So the U.S. intelligence reports predicting that Ashraf Ghani’s puppet government (the term is not too harsh) could fall within six to twelve months of a U.S. troop withdrawal are too optimistic.

The last German, Italian and British troops left Afghanistan last week, and the last US troops are leaving right now, apart from some 650 soldiers to guard the American embassy and the airport. (Always hold the airport, because people lined up on the embassy roof waiting for the last helicopter out is a bad look.)

But Kabul may fall in a lot less than six months. The Taliban already hold at least half the country and they are currently taking new districts literally every day, including ones only an hour’s drive north and south of the capital. The army is just melting away, and the air force will be grounded within weeks once the foreign technical support goes home.

It took almost three years after the Soviet Union pulled out of Afghanistan in 1989 for the local Communist regime to be driven from power by the mujahideen (formerly armed and paid by the United States).

The mujahideen then fell out among themselves, and there was another four years of civil war before the Taliban finally defeated the other groups and took power in Kabul in 1996. And they never controlled the whole country: most Taliban were Pashtuns, and rival ethnic militias held on in the northern provinces until the US invasion in 2001.

The mujahideen group that became the Taliban spent ten years fighting the Russian occupation, then seven years fighting the local regime and rival mujahideen groups; then five years in power; and then another twenty years fighting the US occupation. Unsurprisingly, they have learned a few things in that time.

Most importantly, they have expanded their membership and influence among the non-Pashtun groups: the northern provinces that are now falling to them so fast are the areas they never controlled during their last time in power. They will not just win quickly this time. They will win completely.

Then there will be a period of vengeance-taking in which ‘traitors’ who worked for the Americans or other NATO countries will be hunted down and killed.

Women will be driven out of the workforce, girls’ schools will be closed, music will be banned, and men will be beaten for not wearing beards. The wicked foreign behaviours that were introduced by the Russian occupation and brought back by the U.S. occupation will be expunged, and the Taliban’s extreme version of Islam will reign unchallenged.

It is a tragedy for Afghanistan, but it won’t really matter much for the world. The Taliban have never had any interest in the rest of the world. Their agenda was and still is entirely domestic and religious: make Afghanistan a properly God-fearing place, and all the other good things will follow automatically.

The notion that Afghanistan will become a major terrorist base again once the Taliban regain power is based on the foolish belief that it was an important base for terrorist activity the first time around. Terrorists don’t actually need ‘bases’; the essence of the enterprise is to be invisible until you strike, and the weapons you need are neither large nor hard to obtain.

Most of the 9/11 hijackers got some ‘training’ in Osama bin Laden’s camp, but they were Arabs, not Afghans, and how much training do you need to hijack an airplane? Well, OK, four of them needed flight training, but they did that in the United States.

Bin Laden was only in Afghanistan because American pressure got him expelled from his previous ‘base’ in Sudan. The Taliban leader, Mullah Omar, let him set up in Kandahar because the two men had become close friends when working in the 1980s in the American-backed jihad against the Russians in Afghanistan.

But did Bin Laden tell Omar about his plan to kill thousands of Americans by hijacking commercial aircraft? The first principle of all secret work is ‘need to know’, and Omar didn’t need to know. Indeed, he might have objected if he did know, because he would have realised that Afghanistan would get invaded if the 9/11 attack went ahead.

Afghanistan wasn’t a ‘major terrorist base’ in the past, and it probably won’t become one in the future. And if it does, so what? At least then you’ll know where they are.
