When the U.S. invaded Afghanistan, most American have supported it, just to satisfy their arrogance that they are superpower in the world. Today, most American want the U.S. to withdraw from the war in Afghanistan without the win, because of the recession? In both cases, they have little knowledge of its causes and consequences? For me, the withdrawal of the war in Afghanistan by the United States will bring more economic upheaval, social and political his people that the war in Afghanistan continues. 

Consider why the U.S. is interfering in the affairs of Afghanistan and Pakistan over the past three decades and spend a lot of U.S. $. Billion accounts defense secrets? Pakistan is the gateway to Afghanistan. Afghanistan is on the border with Iran, Turkistan and Tajikistan- big treasure of rare minerals and natural gas.. Afghanistan is considered entry point to Muslim world. 

 Republic of Afghanistan came into existence in 1973 by a non-violent coup against the king with the help of neighboring Russia; he proposed replacing religious and traditional laws with secular and Marxist-Leninist. Republic of Afghanistan called the Soviet Union to assist in the exploration and mining of rare minerals and natural gas. The Soviet Union also sent contractors to build roads, hospitals and schools and to drill water wells and have also trained and equipped Afghan army, the Soviet Union has invested several billion dollars in Afghanistan. Meanwhile, the Communists Soviet Union imposed a tyranny upon the people of Afghanistan. Many members of academia and ethnic minorities in Afghanistan were killed, tortured or imprisoned. Human Rights Watch estimates that as many as 100,000 people may have been killed in the only Republic of Afghanistan by government troops supported by Soviet Union. Thus, Soviet becomes unpopular with a majority of Afghans, as is currently with the United States. 

In 1980, the U.S. saw the situation as an opportunity to weaken the Soviet Union in Republic of Afghanistan. United States began to covertly fund and train anti-government Mujahideen forces through the Pakistani secret service known as Inter Services Intelligence (ISI).  To maintain its influence in Afghanistan, more than 100,000 Soviet soldiers took part in the invasion, was supported by another several hundred thousand soldiers in Afghanistan. 

Some reports estimated that 20 billion dollars had been spent by the United States and Saudi Arabia for funding and arming of the Afghanistan Mujahideen who began a guerrilla war against the Soviet Union forces in Afghanistan. United States support included more two thousand FIM-92 Stinger surface to air missiles, for the establishment of Islamist groups against the Soviet Union. The United States supports most of its support through Pakistan's ISI. Saudi Arabia was also financial support. 

wikipedia.org said that ten years of Soviet occupation of Afghanistan resulted in the killing of ethnic Afghans  600,000 - two million Afghans, mostly civilians. Approximately 6 million Afghans fled to Pakistan and Iran, and from there he made more than 38,000 U.S. and thousands more to the European Union. Faced with international pressure and mass casualties on both sides, the Soviets withdrew in 1989.  Soviet Union withdrawal from Afghanistan was considered an ideological victory in the U.S., which backed Mujahideen factions to counter Soviet influence in the vicinity of the oil-rich Persian Gulf.  
Over the past decade, Afghanistan has its dictate from Mujahideen in Afghanistan and Pakistan in association with the ISI. They do not accept interfere of the U.S. as they did not accept Russia. This is not acceptable to the United States; it has invested several billions of dollars in Afghanistan and Pakiatan. This  created a gap between the U.S. and Pakistan-Afghanistan Mujahideen now called- Al Qaeda or more or groups. This created possibility in the United States to invade Afghanistan, saying Bin Laden is in Afghanistan.. 

When the U.S. invaded Afghanistan, its people have supported it, just to satisfy their arrogance that they are superpower in the world. Today, most people want the U.S. to withdraw from the war in Afghanistan without the win, because of the recession? For me, the withdrawal of the war in Afghanistan by the United States will bring more economic upheaval, social and political his people that the war in Afghanistan continues. 

Now, Iran and China has seen the situation as an opportunity to weaken U.S. interests in Afghanistan and neighboring, Turkistan and Tajikistan. Iran is investing in gas pipeline to Pakistan through Afghanistan and supporting Balochistan freedom struggle on border of Afghanistan  . China has now declared invest heavily in Pakistan bordering Afghanistan. Pakistan is getting closer to China than the United States.  Now Pakistan and Afghanistan people respect more to China than United States. History is bound to repeat in Afghanistan by China on the withdrawal of forces from Afghanistan by United States. 

The question is whether the U.S. should withdraw its forces from Afghanistan? To me, he should stop spending huge war, but not withdraw its troops. It should support the infrastructure of roads, education and employment. It must develop to their well-being of common people of Afghanistan, without interfering lifestyle and religious sentiments..  Most of Telephone exchange, Radio, T.V, Hospitals and Educations and Roads system in operation in Afghanistan is donated by India. It is run by Afghanistan people , but trained free of cost in India. This is what India is doing since many years. Economic Times says that India has spend U.S.$ 1.3 Billion recently in reconstruction of Afghanistan. So common people of Afghanistan have no hate against India. Killing  militants by drones of U.S. is coward act  and it also kills many innocent people  and is sowing seed of more militants and suicide bombers.

Many people in the United States believe that Afghanistan is far from the United States, safe from the Afghanistan Mujahedin. It should immediately withdraw its troops.  Pakistan-Afghanistan Mujahideen has attained machinery and technology to print  quality currency of most country including US $ and Rupee India and  have become major supplier of pirated grade of arms, which are openly available for sale middle east . The Pakistan-Afghan border has already become a training center for piracy, hackers and currency printing of all major countries. Low help to Afghanistan will make Pakistan-Afghanistan Mujahideen to capture the assets of nuclear technology from Pakistan and sell it worldwide as the potatoes on vegetable shop.

 Withdrawal of U.S. forces in Afghanistan, it will make it the ground of stateless actors and loss of influence in the Middle East. Losing war to evil is more dangerous than continue fighting it.  United States has to spend more on its internal security than on war in Afghanistan.  Common American is already is already under fear while at  its airports, sensitive installation and unknown neighbor. Economic upheaval, social and political effects and security risk is seen on face of its people .  This is what Pakistan-Afghanistan Mujahideen want; call them supporter of Bin Laden or Al Qaeda or more or ethnic islamic groups.
