Usually with a question this nebulous, it would be impossible to answer it. However, interestingly enough, the upwards of 15 invasions of Afghanistan (excepting the US invasion in 2001) were all reasoned on account of its strategic position. (There was never a desire to hold Afghanistan for its people, resources, or for religious reasons.)
The Strategic Rationale: Afghanistan is well placed at the crossroads of 4 major regions/empires: Persia in the West, China in the East, Russia/Soviet Union in the North, and India/Pakistan in the South. As a result of its central location and relatively good defensibility (Afghanistan is very mountainous), many different leaders wanted to conquer it to use its territory to conquer another one of Afghanistan's more desirable neighbors.
The United States Invasion: The US Invasion of Afghanistan in 2001 was to hunt down the terrorists responsible for the events of 9-11 (Al-Qaeda and its affiliates) and the regime that protected them.
After the September 11 attacks in 2001, sentiment in the US increased to stop the activities of terrorists, under the general name of the War on Terrorism. Because the Taliban had taken over Afghanistan, and given support to Osama bin Laden and Al-Qaeda, they were the first targets. The US supported the anti-Taliban factions, which eventually took control of the majority of the country.
Because We Afghans were and are week and will remain week.
