paragraph_text: Immunology is strongly experimental in everyday practice but is also characterized by an ongoing theoretical attitude. Many theories have been suggested in immunology from the end of the nineteenth century up to the present time. The end of the 19th century and the beginning of the 20th century saw a battle between "cellular" and "humoral" theories of immunity. According to the cellular theory of immunity, represented in particular by Elie Metchnikoff, it was cells – more precisely, phagocytes – that were responsible for immune responses. In contrast, the humoral theory of immunity, held, among others, by Robert Koch and Emil von Behring, stated that the active immune agents were soluble components (molecules) found in the organism’s “humors” rather than its cells.

paragraph_text: In Afghanistan, the mujahideen's victory against the Soviet Union in the 1980s did not lead to justice and prosperity, due to a vicious and destructive civil war between political and tribal warlords, making Afghanistan one of the poorest countries on earth. In 1992, the Democratic Republic of Afghanistan ruled by communist forces collapsed, and democratic Islamist elements of mujahdeen founded the Islamic State of Afghanistan. In 1996, a more conservative and anti-democratic Islamist movement known as the Taliban rose to power, defeated most of the warlords and took over roughly 80% of Afghanistan.

paragraph_text: The dominance of the nomads ended in the 16th century as firearms allowed settled people to gain control of the region. The Russian Empire, the Qing dynasty of China, and other powers expanded into the area and seized the bulk of Central Asia by the end of the 19th century. After the Russian Revolution of 1917, the Soviet Union incorporated most of Central Asia; only Mongolia and Afghanistan remained nominally independent, although Mongolia existed as a Soviet satellite state and Soviet troops invaded Afghanistan in the late 20th century. The Soviet areas of Central Asia saw much industrialisation and construction of infrastructure, but also the suppression of local cultures and a lasting legacy of ethnic tensions and environmental problems.

They were accused of training to assist the Taliban's military. They were cleared as safe for release from Guantánamo in 2005 or 2006, but US domestic law prohibited deporting them back to China, their country of citizenship, because the US government determined that China was likely to violate their human rights.

paragraph_text: From 1996 to 2001, the Taliban held power over roughly three quarters of Afghanistan, and enforced there a strict interpretation of Sharia, or Islamic law. The Taliban emerged in 1994 as one of the prominent factions in the Afghan Civil War, and largely consisted of students recently trained in madrassas in Pakistan. Under the leadership of Mohammed Omar, the movement spread throughout most of Afghanistan, sequestering power from the Mujahideen warlords. The Islamic Emirate of Afghanistan was established in 1996 and the Afghan capital transferred to Kandahar. It held control of most of the country until being overthrown by the American - led invasion of Afghanistan in December 2001 following the September 11 attacks. At its peak, formal diplomatic recognition of the Taliban's government was acknowledged by only three nations: Pakistan, Saudi Arabia, and the United Arab Emirates. The group later regrouped as an insurgency movement to fight the American - backed Karzai administration and the NATO - led International Security Assistance Force (ISAF).

paragraph_text: The Rohingya people have consistently faced human rights abuses by the Burmese regime that has refused to acknowledge them as Burmese citizens (despite some of them having lived in Burma for over three generations)—the Rohingya have been denied Burmese citizenship since the enactment of a 1982 citizenship law. The law created three categories of citizenship: citizenship, associate citizenship, and naturalised citizenship. Citizenship is given to those who belong to one of the national races such as Kachin, Kayah (Karenni), Karen, Chin, Burman, Mon, Rakhine, Shan, Kaman, or Zerbadee. Associate citizenship is given to those who cannot prove their ancestors settled in Myanmar before 1823, but can prove they have one grandparent, or pre-1823 ancestor, who was a citizen of another country, as well as people who applied for citizenship in 1948 and qualified then by those laws. Naturalized citizenship is only given to those who have at least one parent with one of these types of Burmese citizenship or can provide "conclusive evidence" that their parents entered and resided in Burma prior to independence in 1948. The Burmese regime has attempted to forcibly expel Rohingya and bring in non-Rohingyas to replace them—this policy has resulted in the expulsion of approximately half of the 800,000 Rohingya from Burma, while the Rohingya people have been described as "among the world's least wanted" and "one of the world's most persecuted minorities." But the origin of ‘most persecuted minority’ statement is unclear.

paragraph_text: Immediately after the attacks, General Tommy Franks, then - commanding general of Central Command (CENTCOM), initially proposed to President George W. Bush and Secretary of Defense Donald Rumsfeld that the U.S. invade Afghanistan using a conventional force of 60,000 troops, preceded by six months of preparation. Rumsfield and Bush feared that a conventional invasion of Afghanistan could bog down as had happened to the Soviets and the British. Rumsfield rejected Franks's plan, saying ``I want men on the ground now! ''Franks returned the next day with a plan utilizing U.S. Special Forces. On September 26, 2001, fifteen days after the 9 / 11 attack, the U.S. covertly inserted members of the CIA's Special Activities Division led by Gary Schroen as part of team Jawbreaker into Afghanistan, forming the Northern Afghanistan Liaison Team. They linked up with the Northern Alliance as part of Task Force Dagger.

paragraph_text: Support for the U.S. cooled when America made clear its determination to invade Iraq in late 2002. Even so, many of the "coalition of the willing" countries that unconditionally supported the U.S.-led military action have sent troops to Afghanistan, particular neighboring Pakistan, which has disowned its earlier support for the Taliban and contributed tens of thousands of soldiers to the conflict. Pakistan was also engaged in the War in North-West Pakistan (Waziristan War). Supported by U.S. intelligence, Pakistan was attempting to remove the Taliban insurgency and al-Qaeda element from the northern tribal areas.

paragraph_text: During the 19th century, Britain and the Russian Empire vied to fill the power vacuums that had been left by the declining Ottoman Empire, Qajar dynasty and Qing Dynasty. This rivalry in Eurasia came to be known as the "Great Game". As far as Britain was concerned, defeats inflicted by Russia on Persia and Turkey demonstrated its imperial ambitions and capabilities and stoked fears in Britain of an overland invasion of India. In 1839, Britain moved to pre-empt this by invading Afghanistan, but the First Anglo-Afghan War was a disaster for Britain.

paragraph_text: The War in Afghanistan (or the U.S. War in Afghanistan; code named Operation Enduring Freedom -- Afghanistan (2001 -- 2014) and Operation Freedom's Sentinel (2015 -- present)) followed the United States invasion of Afghanistan of October 7, 2001. The U.S. was supported initially by the United Kingdom and Canada and later by a coalition of over 40 countries, including all NATO members. The war's public aims were to dismantle al - Qaeda and to deny it a safe base of operations in Afghanistan by removing the Taliban from power. The War in Afghanistan is the second longest war in United States history, behind the Vietnam War.
