War on Afghanistan: Logical result of unsuccessful struggle by the U.S. to build pipelines through it? published on Al Jazeera.com, by RUDO de RUIJTER, February 9, 2007.
This is a research article by Rudo de Ruijter, containing about a hundred facts leading ultimately to the U.S. war against Afghanistan. For each of them reliable sources are mentioned. It is a disturbing article, if you don’t know these facts yet. (For fair use, you may publish and/or forward this article).
Short content: This article is about backgrounds of the U.S. war against Afghanistan. It is about oil, gas and pipelines around the Caspian Sea. To transport oil and gas from the east side of the Caspian Sea, pipelines had been planned through Afghanistan. Because a U.S. company, UNOCAL, failed to control the Afghan route, the war was prepared. When the military was ready to strike, the “terrorists” of 9/11 gave Bush the pretext to start this war and obtain support from Congress, the U.S. population and the rest of the world.

Preparations for 9/11 and the invasion of Afghanistan
Our politicians have shaped the idea many people have about our world. They have divided our world into good and bad. Of course, they are always the good guys and the ones they accuse are the bad guys. Simple, isn’t it?
However, if we stick to the facts, and throw out all the information that comes from unverifiable sources, our world looks very different. This research is not meant to offend anyone. If you are pleased with the “official” version of our history, don’t read any further.
Bush said the attacks of 9/11 were the reason to invade Afghanistan. 
This article shows that the war was the logical result of an unsuccessful struggle, by the U.S., to build and control pipelines through Afghanistan, and that preparations for this war took place before 9/11.
In 2000 the neoconservatives said they needed some catastrophic and catalysing event.
This article shows how this event may have taken place on September 11, 2001.
The 1993 attack:
The attacks on the World Trade Centre and the Pentagon on September 11, 2001 eclipse an earlier attack on the World Trade Centre in 1993. On January 20 1993, William (Bill) Clinton had become President. A month later, on February 26, an “immense blast happened at 12:18 local time in the Secret Service’s section of the car park underneath and between what are New York’s tallest buildings.” 
BBC published the words of an eyewitness: “It felt like an airplane hit the building.” Apparently the explosion was intended to bring both WTC towers down. The New York Times found out that the FBI was involved in the attacks. The FBI would have infiltrated a group of “terrorists”, would have known about their intentions and for some unknown reason let it happen.  Six people died and a hundred were injured. 
Timeline 1989 – 2000:
In this chapter I will present a timeline of Afghan events. I will also mention events related to terrorism, which will become U.S. final pretext for war.
Immediately after the attacks on September 11, 2001, U.S. officials accused Osama bin Laden. Since the man would reside in Afghanistan, it provided a pretext for George W. Bush to attack and invade Afghanistan.
Let’s have a closer look at the situation prior to 9/11. As promised by Soviet president Mikhail Gorbachev, the USSR had withdrawn its last soldiers from Afghanistan on February 15, 1989. It was the end of ten years of war. It was also the last war of the Soviet Union.
A few months later, on November 9, 1989, the Berlin wall fell. The Iron Curtain broke down. The people living on the other side of the curtain, of whom our leaders had always pretended they were dangerous and ferocious, turned out to be as friendly as us.
With the concept of the Cold War our leaders had divided our world and maintained fear in our minds for over forty years. This terror, fabricated by our own governments, was finally over.
