Is U.S. Set to Invade Pakistan?

Seeing as I live in the UK, I'd have to have very good ears.

The Taliban actually shot people for growing opium.

Soviet period (1979–1989)
As the Afghan government began to lose control of provinces during the Soviet invasion of 1979-80, warlords flourished and with it opium production as regional commanders searched for ways to generate money to purchase weapons, according to the UN. (At this time the US was pursuing an "arms-length" supporting strategy of the Afghan freedom-fighters or Mujahideen, the main purpose being to cripple the USSR slowly into withdrawal through attrition rather than effect a quick and decisive overthrow.)
In 1995 the former CIA Director of this Afghan operation, Mr. Charles Cogan, admitted sacrificing the drug war to fight the Cold War. "Our main mission was to do as much damage to the Soviets. We didn't really have the resources or the time to devote to an investigation of the drug trade," he told Australian television. "I don't think that we need to apologize for this. Every situation has its fallout. There was fallout in terms of drugs, yes, but the main objective was accomplished. The Soviets left Afghanistan."

As explained by Zbigniew Brzezinski:
The secret operation was an excellent idea. It drew the Russians into the Afghan trap and you want me to regret it? On the day that the Soviets officially crossed the border, I wrote to President Carter, saying, in essence: 'We now have the opportunity of giving to the USSR its Vietnam War.'

It was alleged by the Soviets on multiple occasions that American CIA agents were helping smuggle opium out of Afghanistan, either into the West, in order to raise money for the Afghan resistance or into the Soviet Union in order to weaken it through drug addiction. According to Alfred McCoy, the CIA supported various Afghan drug lords, for instance Gulbuddin Hekmatyar[8][12] and others such as Haji Ayub Afridi.

Warlord period (1989–1994)
When the Soviet Army was forced to withdraw in 1989, a power vacuum was created. Various Mujahideen factions started fighting against each other for power. With the discontinuation of Western support, they resorted ever more to poppy cultivation to finance their military existence.

Rise of the Taliban (1994–2001)
During the Taliban rule, Afghanistan saw a bumper opium crop of 4,500 metric tons in 1999,. However, in July 2000, Taliban leader Mullah Mohammed Omar, collaborating with the United Nations to eradicate heroin production in Afghanistan, declared that growing poppies was un-Islamic, resulting in one of the world's most successful anti-drug campaigns. As a result of this ban, opium poppy cultivation was reduced by 91% from the previous year's estimate of 82,172 hectares. The ban was so effective that Helmand Province, which had accounted for more than half of this area, recorded no poppy cultivation during the 2001 season.

Present War in Afghanistan
Opium production levels for 2005-2007
By November 2001, the collapse of the economy and the scarcity of other sources of revenue forced many of the country's farmers to resort back to growing opium for export.(1,300 km² in 2004 according to the United Nations Office on Drugs and Crime.)

In December 2001, a number of prominent Afghans met in Bonn, Germany, under United Nations (UN) auspices to develop a plan to reestablish the State of Afghanistan, including provisions for a new constitution and national elections. As part of that agreement, the United Kingdom (UK) was designated the lead country in addressing counter-narcotics issues in Afghanistan. Afghanistan subsequently implemented its new constitution and held national elections. On December 7, 2004, Hamid Karzai was formally sworn in as president of a democratic Afghanistan."

Two of the following three growing seasons saw record levels of opium poppy cultivation. Corrupt officials may have undermined the government's enforcement efforts. Afghan farmers suggested that "government officials take bribes for turning a blind eye to the drug trade while punishing poor opium growers".
Another obstacle to getting rid of poppy cultivation in Afghanistan is the reluctant collaboration between US forces and Afghan warlords in hunting drug traffickers. In the absence of Taliban, the warlords largely control the opium trade but are also highly useful to the US forces in scouting, providing local intelligence, keeping their own territories clean from Al-Qaeda and Taliban insurgents, and even taking part in military operations.
Former U.S. State Department Principal Deputy Assistant Secretary for the Bureau of International Narcotics and Law Enforcement Affairs Thomas Schweich, in a New York Times article dated July 27, 2007, asserts that opium production is protected by the government of Hamid Karzai as well as by the Taliban, as all parties to political conflict in Afghanistan as well as criminals benefit from opium production, and, in Schweich's opinion, the U.S. military turns a blind eye to opium production as not being central to its anti-terrorism mission. In March 2010, NATO rejected Russian proposals for Afghan poppy spraying, citing concerns over income of Afghani people. There have also been allegations of American and European involvement in Afghanistan's drug trafficking with links to Taliban.
On October 28, 2010 agents of Russia’s Federal Service for the Control of Narcotics joined Afghan and American antidrug forces in an operation to destroy a major drug production site near Jalalabad. In the operation 932 kg (2,055 lb) of high quality heroin and 156 kg (345 lb) of opium, with a street value of US$ 250 million, and a large amount of technical equipment was destroyed. This was the first anti-drug operation to include Russian agents. According Viktor Ivanov, Director of Russia’s Federal Service for the Control of Narcotics, this marks an advance in relations between Moscow and Washington. Afghan President Hamid Karzai called the operation a violation of Afghan sovereignty and international law.

Foreign Involvement
Approximately 40,000 foreign troops help manage security in Afghanistan, principally of 32,000 regular soldiers from 37 North Atlantic Treaty Organization (NATO) forces: the International Security Assistance Force. 8,000 US and other special operations forces make up the balance. There is significant resistance, both from the ideological/theocratic Taliban, especially in southern Afghanistan, and also independent local warlords and drug organizations. Antonio Maria Costa, Executive Director of the United Nations Office on Drugs and Crime (UNODC), described the situation this way: "There is no rule of law in most of the southern parts of Afghanistan—the bullets rule."

Afghanistan has been the greatest illicit opium producer in the entire world, ahead of Burma (Myanmar) and the "Golden Triangle" since 1992, excluding the year 2001[1]. Afghanistan is the main producer of opium in the "Golden Crescent". Opium production in Afghanistan has been on the rise since U.S. occupation started in 2001. Based on UNODC data, there has been more opium poppy cultivation in each of the past four growing seasons (2004–2007) than in any one year during Taliban rule. Also, more land is now used for opium in Afghanistan than for coca cultivation in Latin America. In 2007, 92% of the opiates on the world market originated in Afghanistan. This amounts to an export value of about $4 billion, with a quarter being earned by opium farmers and the rest going to district officials, insurgents, warlords, drug traffickers. In the seven years (1994–2000) prior to a Taliban opium ban, the Afghan farmers' share of gross income from opium was divided among 200,000 families. In addition to opiates, Afghanistan is also the largest producer of hashish in the world.

Opium production has fallen greatly since 1906, when 41,000 tons were produced, but because 39,000 tons of that year's opium were consumed in China, overall usage in the rest of the world was much lower. These figures from 1906 have been criticized as over-estimates. In 1980, 2,000 tons of opium supplied all legal and illegal uses. Recently, opium production has increased considerably, surpassing 5,000 tons in 2002. The World Health Organization has estimated that current production of opium would need to increase fivefold to account for total global medical need.

In 2002, the price for one kilogram of opium was $300 for the farmer, $800 for purchasers in Afghanistan, and $16,000 on the streets of Europe before conversion into heroin.

Afghanistan is currently the primary producer of the drug. After regularly producing 70% of the world's opium, Afghanistan decreased production to 74 tons per year under a ban by the Taliban in 2000, a move which cut production by 94 per cent. A year later, after American and British troops invaded Afghanistan, removed the Taliban and installed the interim government, the land under cultivation leapt back to 285 square miles (740 km2), with Afghanistan supplanting Burma to become the world's largest opium producer once more. Opium production in that country has increased rapidly since, reaching an all-time high in 2006. According to DEA statistics, Afghanistan's production of oven-dried opium increased to 1,278 tons in 2002, more than doubled by 2003, and nearly doubled again during 2004. In late 2004, the U.S. government estimated that 206,000 hectares were under poppy cultivation, 4.5% of the country's total cropland, and produced 4,200 metric tons of opium, 76% of the world's supply, yielding 60% of Afghanistan's gross domestic product. In 2006, the UN Office on Drugs and Crime estimated production to have risen 59% to 407,000 acres (1,650 km2) in cultivation, yielding 6,100 tons of opium, 82% of the world's supply.[88] The value of the resulting heroin was estimated at $3.5 billion, of which Afghan farmers were estimated to have received $700 million in revenue. For farmers, the crop can be up to ten times more profitable than wheat. The price of opium is around $138 per kilo. Opium production has led to rising tensions in Afghan villages. Though direct conflict has yet to occur, the opinions of the new class of young, rich men involved in the opium trade are at odds with those of the traditional village leaders.
