Two Clarifiers:
1) Terrorism cannot be stopped as it is merely a method of warfare but the terrorists themselves can be.
1.5) Islamism is not Islam, I want to make sure that you understand the difference here, Islam is a religion but Islamism is a Political Ideology (not a religion) that entails using the Quaran and Sharia law as the rules of the state and to create a theocratic regime just like the Taliban in afghanistan. It is very similar to Fascism, one could see it as a global form of fascism in a globalised world.
2) I wanted to draw attention to parallells between Fascism and Islamism because they share simmilarites and Islamism can aptly be described as Islamofascism, it is not some sort of right wing nutter lunar conspiracy term without any base in reality rather a legitmate statement about the true nature of fundamentalist islam and the way it operates in the world.
The Islamism (which entails having the state become a religous entity and all peple are subservient to is) is what I am talking about, we can stop Islamism but it takes a lot of work and it must be fought on every front.
Millitary action is a critical element of this, look at what happens when you don't meet them with a strong response, Since the 1960's and particularly in the 1990's you had a string of related terrorist atttacks all of growing magnitude that did not illicit a strong millitary response. By not fighting them and instead waiting for the terrorists to strike again emboldened them and it culminated in September 11. When you don't react it is seen as a sign of weakness and will only encourage them to take another inch, this in what we saw on September 11, the natural progression from Leaving Somalia in discrace to the Trade Center Car Bombing in '93 to the aborted Operation Bojinka in '95 to the Embassy Bombings in '98 to the USS Cole in 2000. Each time there was an attack the US response was piss weak and it the terrorists were essentially allowed to continue to build a support base and escelate without the threat of retribution or intervention. If the US was to have taken a stronger millitary action against Al Qaeda in the 1990's I am certain the September 11 would never have occured, this is all of course hypothetical however I am just making the point that the terrorists see any capitulation or lack of will as a sign of weakness and they will sieze upon it as another example of the weakness of the west and the sucess they have in fighting us. By choosing to fight the terrorists on our terms in a so called "war on terror" Bush has no doubt prevented another escelation of attack. which would probably have involved CBR weapons. If it wasnt for this agressive campaign of fighting the terrorists with all tools at our disposal then we would not be sitting here in mid 2004 without having experienced a major terrorist attack on US soil since 9/11.
Millitary might is not the only way to fight the terrorists though as it must be coupled with a very strong intelligence service, here is where you need to have your echelon programs that can take in massive ammounts of sigint (Signals Intelligence) and locate any potential terrorist threats as well as key Al Qaeda members. This is equally as important as being able to take millitary action against terrorists.
Thirdly we must remove the hate filled ideology that comes out of the ME and stop it from producing Jihadists, Saudi Arabia is a classic example of a Gulf State that has too much money, is totally corrupt and sends its children off to wage holy war all over the world in the name of spreading its islamist version of Islam known as wahhabism. If we could get these countries to embrace concepts such as secularism and education, reason and cultural openness then they would inevitably stop producing terrorists and terrorist sympathisers. As a whole Islam the religion and culture needs to be brought into the modern world and when it does the hate filled fascist concepts of Islamism will be left in the past where they should remain.
