During the Soviet-Afghan war in the 1980s, the Afghan guerrillas had the great advantage of being able to retreat to safe bases in neighbouring Pakistan if Russian military pressure became too great. With the USA supporting Pakistan, there was never any chance the Soviet Union would attack those bases and risk a major crisis between the superpowers.
Today the Taliban militants operating against Western forces in Afghanistan run their operations from bases in the regions of Pakistan along the Afghan border. These safe havens are chiefly in northern Balochistan and the so-called Federally Administered Tribal Areas, especially North and South Waziristan. Other than occasional airstrikes, chiefly by Predator UAVs, the Americans have been reluctant to take direct military action against these Taliban and al-Qaeda bases in Pakistan. Instead the USA has encouraged the Pakistani government to suppress them.
So far such Pakistani military efforts have met with only limited success, and there have been increasing calls in some quarters for the USA and its Western allies to undertake direct military action against terrorist bases in the border areas of Pakistan, above all in Waziristan. Such calls must be resisted since for the West to invade a Muslim nation for the third time since 2001 (the other invasions being Afghanistan and Iraq) would only further inflame hatred of the USA and its Western allies in the Islamic world.
The tribesmen of Waziristan have successfully resisted foreign invaders for centuries. Even the British Raj had to recognise their semi-independent status in 1893. However, this did not stop clashes between the two sides. For example, after the short-lived Third Anglo-Afghan War in 1919, a considerable revolt broke out in Waziristan. British and Indian forces suffered more than two thousand casualties before they forced the tribesmen to make peace in March 1920. Nevertheless further clashes, large and small, continued in Waziristan up until 1947 when Britain could hand the problem area over to newly independent Pakistan.
The Pakistanis avoided serious trouble in Waziristan largely by leaving the local people to run their own affairs. However, after 9/11 and the US-led invasion of Afghanistan, Taliban and al-Qaeda remnants, including leaders such as Mullah Omar and Osama bin Laden, fled across the border into Waziristan and adjacent areas. Under American pressure, the ruler of Pakistan, General Pervez Musharraf, was compelled to send large numbers of troops into North and South Waziristan for the first time in decades. These forces had comparatively little success in rounding up Taliban and al-Qaeda militants, but their presence did anger local tribesmen, leading to increasing clashes between the two sides.
In March 2004 these clashes escalated into an open war between the Pakistani forces on one side and local tribesmen, Taliban guerrillas, and al-Qaeda fighters (mostly foreign) on the other. By the time a peace accord was finally negotiated between the contesting parties in September 2006, an estimated 700 Pakistani troops had been killed, as well as 1,000 militants and 1,000 civilians.
Although fragile, the peace accord did give the Pakistani authorities a chance to exploit divisions among their opponents. Relations between local people and foreign Islamist fighters had not always been good, and in the spring of 2007 violence broke out between local tribesmen and Uzbek fighters linked to al-Qaeda. By mid-April the Uzbeks had been largely driven out of South Waziristan, with Pakistani artillery assisting local tribesmen in some of their attacks.
These favourable developments might have led to further attacks on foreign Islamist fighters in the area, but in July 2007 Musharraf's government enraged radical Islamists all over Pakistan by its clumsy and bloody suppression of militant activity at the Red Mosque in the capital Islamabad. The Waziristan peace accord collapsed and between July and November 2007 there was intense fighting in the region, with suicide bombers taking a new prominence in attacks on Pakistani forces. By early 2008 the estimated casualties after barely six months of fighting exceeded those for the whole 2004-06 war: 850 troops killed, as well as 1,900 militants and 1,800 civilians.
Recently the tempo of the fighting has decreased and the new civilian government of Pakistan is promising to negotiate a peaceful settlement in Waziristan and adjacent areas rather than using further military force. The US government has expressed concern about this approach and some commentators have now suggested the Americans and their allies may have to intervene directly in Waziristan to destroy terrorist bases, with or without the approval of the Pakistani government in Islamabad. Such Western intervention, even if only in the form of increased airstrikes and raids by special forces, can only further inflame the situation in the region.
The only way to root out the Taliban and al-Qaeda from Waziristan and adjacent areas is for the Pakistani government to take action. As shown by the successful efforts against Uzbek fighters in South Waziristan in 2007, the Pakistanis can get local tribesmen to drive out foreign Islamist militants. This is the only way to go. It may not be swift, but it is likely to be effective in the long run. If impatience leads to clumsy Western military intervention in Waziristan, such action is more likely to spread war across Pakistan than to end it in Afghanistan.
