Terrorism is also caused when one country militarily occupies another country. That is, it is the military occupation that provides a lot of terrorists with their goal (i.e. to free their country from foreign military occupation). Chicago political scientist Robert Pape has shown that the vast majority of suicide bombings in the past 30 years have come in response to foreign military occupation (or what the terorists perceived as such). Back in the late 50s and early 60s, the Algerians and the French were locked in such a struggle. The French killed nearly a million Algerians (in a population of 11 million), and the Algerians blew up a lot of French. When the French recognized Algeria as an independent country in 1962, the struggle quickly subsided and by 1963 Algeria wasn't even a big subject in French newspapers.
The Israeli military occupation of Jerusalem, the West Bank and Gaza from 1967 has caused an enormous amount of terrorism in the world. It hasn't been the only such source by any means. The Tamil Tigers, a group based in Sri Lanka (used to be called Ceylon), blew up Indian Prime Minister Rajiv Gandhi and engaged in many other terrorist operations in Sri Lanka and India. It is a Marxist group and in some ways pioneered the suicide bombing. Because Sri Lanka and its concerns seeem so remote to most Americans, most people here don't even know about the Tamil Tigers. But if the US went in and militarily occupied the Tamil parts of Sri Lanka, all of a sudden we'd be seeing bombs go off against US targets. I guarantee it. That is not to say it would be right. But it is to say that that is how reality works (reality cannot be simply manufactured in the White House, contrary to what Scooter Libby thinks).
The Israeli Jerusalem Barrier project will have similar effects. It keeps inside itself a major Israeli settlement on Palestinian land that Sharon has recently announced he will greatly expand (probably using American money at least in part).
Because al-Qaeda and its fellow travelers do not speak in the language of Palestinian nationalism, it has been possible for certain quarters to obscure to the US public that they are absolutely manically fixated on the Israeli occupation of Jerusalem. This is what Bin Laden meant way back in the 1990s when he denounced the foreign military occupation of "the three holy cities." Here is what Bin Laden wrote in 1998 when he declared war on the US:
' Third, if the Americans' aims behind these wars are religious and economic, the aim is also to serve the Jews' petty state and divert attention from its occupation of Jerusalem and murder of Muslims there. The best proof of this is their eagerness to destroy Iraq, the strongest neighboring Arab state, and their endeavor to fragment all the states of the region such as Iraq, Saudi Arabia, Egypt, and Sudan into paper statelets and through their disunion and weakness to guarantee Israel's survival and the continuation of the brutal crusade occupation of the Peninsula.
