Hazza, you are not even trying to understand the very basics.

Here, I will make it a bit easier for you:

http://en.wikipedia.org/wiki/Islamism

Islamist terror groups have been attacking other Muslims and
infidels around the world, for a long time now. From
hijacking the Grand Mosque in Mecca for a week, to blowing
up other muslims who refuse to accept their version of Islam,
to blowing up Australians in Bali, its all part of their
ideology. From Russia to Spain, they have been violent as
part of their struggle for violent jihad.

But its pointless to discuss this, if you even refuse to
understand even the basic ideology which drives them.

Other fuels? The world burns around 85 million barrels
of oil a day. Nearly every tractor and truck on the
planet runs on diesel. If diesel production stops tomorrow,
your food production stops tomorrow and within days you
will go hungry, when those shelves at Coles and Woolies
are bare. That is the reality. Contemplating your navel
about what else might perhaps drive those vehicles one
day, which would take decades to implement, is not going
to produce your food next week, I am afraid.

Stop daydreaming Hazza.

King Hazza sorry not intention to offend you are out of your depth in this subject.
Read the Koran.
Read the claims of these terrorists,see the plans to make a new country part of it would be in our top end.
You do your self a disservice in blaming America this way
And you true, are the very first person I EVER found who is unaware of the living breathing hatred that old war still brings.

You all want a laugh.There was a security conference here in Syd from 1-3 Sept.Nick Caldis the deputy Commissioner of Security for NSW recommended Robert Baer ex CIA to Ray Hadley, who interviewed him at the 2GB studios.Baer was saying it would be almost inevitable that Israel would attack Iran sending oil prices through the roof.If you go to http://patriotsquestion911.com/ On age 48 there is a picture of Robert Baer saying there is evidence that the US Govt was involved in 911.

Thom Hartman; "Are you of the opinion that there is an aspect of Inside job to 911?"

Robert Baer; "There is that possibility.The evidence points to it."

Baer can be also seen on youtube saying this and on Hardtalk in 2008 saying that Iran is in now way a threat to Israel or the Middle East.

Now we have Ex CIA totally contradicting official perceptions of foreign policy and the real perpetrators of 911.

So Stg,Pericles and stevenlmeyer,it is time to suck eggs.

Forget it Yabby, if you're too lazy or incapable to have found out, using the same wikipedia your wahabism source came from, whether the US did actually have an active military role in the Muslim world, whether approximately 44% of world oil was actually OUTSIDE the Middle East, and that we now have vehicles powered by ethanol, fruit/nut oils, hydrogen and direct electricity supplies, then don't be surprised if I find your depth of research very lacking.
And for your information, I have actually read these Koranic hate passages, covering many sources factoring in fundamentalist doctrine into Islamist mindsets. So I know just as much (to say the very least) as you do.

What, were you expecting some lefty who thought wahabis are deep down nice friendly people who are misunderstood because they're hurting?

Belly, to answer your questions;
Many of the terrorist attacks, (in fact, almost all) were committed locally by locals; the terrorist simply conspired with nearby neighbours to create materials, and they targeted some locally-accessible people they hated. This is based on something they felt affected them, their culture or their community. Most importantly, they were independent, and unrelated, to the Taliban. In other words, naught but local attempts to rebel or gain ground within the country (Iraq sectarian violence), or a local hate crime (Bali, committed by East-Javanese)

However, virtually every single international terrorist attack was committed locally by somebody we willingly let in, and always the same political targets. And again, hardly any actually done by Al Queda (and zero by the Taliban, though they were happy to house the terrorists and protect them)- the rest were independent groups.

The only way these people are able to, and motivated enough to attack is because we keep exposing ourselves to them. By interracting we just raise our profile over there.

*we now have vehicles powered by ethanol, fruit/nut oils, hydrogen and direct electricity supplies*

Fruit/nut oils Hazza? How far do you think that will get you lol.
How many vehicles and production facilities do you have, ready
to go? It only needed the world demand/supply to be out of
balance by a small amount, for the oil price to double. Take
out 20 million barrels a day and what do you think would happen?
The West would bankrupt itself trying to pay for the % that
is left.

We are still hooked on ME oil, even George Bush, who was not
your smartest puppy, accepted and acknowledged that.

Yes, the Americans had a base in Saudi Arabia and still have
bases in Kuwait etc, at the invitation of Arab Govts. For
it was these Govts who were threatened by Saddam Hussein.

So what? The notion that terrorism will go away if America
leaves is a flawed one.

You claim to know so much about all this, why don't you understand
the difference between Wahabbis and Salafist jihadis and the
ideology that drives the latter?

Of course most terror groups act locally. They don't have the money
that bin Laden inherited from his extremely rich father.

But the band of Arab salafists don't act locally. They move around
and they have money. They are involved from Chechnya, to Afghanistan
to the Sudan. Afghanistan became their main training ground and a
base. Many originally went there to fight the Russians. There's
is a political-ideological war, for Islam is a political religion.

Their intention is a global Caliphate, as suggested by their
ideological leaders, such as Qutb. They want to take Islam back
to be the power that it once was.

You are not even going to be able to ban them from travelling to
the West, as the West has open societies and cannot just ban all
Muslims. For most of them are not violent jihadis.

Yabby, there's coconut oil vehicles- look it up. It actually provides a perfect substitute for oil in warm climates (eg tropical Australia), and ethanol- whose only downside is that commercial trading raises the price of corn. electric Cars are already in use in much of Northern Europe, whose limitations are the requirement that society simply invest in recharge infrastructure.
There's your alternate fuel nailed "lol".
And I don't suppose George Bush's insistence on oil dependency had anything to do with the fact that his family, and their top business partners own oil companies? You seem to fail to factor considerations of lobbyists into your presumptions of reality.
This is rather basic knowledge.

Anyway, your examples of 'worldwide caliphate' are all still falling under my own category of motive;
Strangely, the only attacks we have encountered where the terrorists have travelled to our countries specifically to launch an attack, were all connected in that they demanded the withdrawal of the infidel from a Muslim country, or over some other transgression committed by an infidel against a Muslim. This is reinforced by the fact that there are plenty of smaller infidel countries that make little allowance to Islam in comparison who, for some reason, don't receive international attacks, coincidentally corresponding to their scarcer political presence in the Middle East!

And keeping out extremists?
Plenty of ways, enforcing secularist conduct laws such as banning items that only fundamentalists need to function (such as Burqas), and generally having the balls to refuse entry to someone who passes off as a security threat, isn't secular, or holds anti-western, anti-semetic views, achievable by some simple interview tests and monitoring their response, as opposed to solely a proven member of certain terrorist groups (hardly any WE actually ban ourselves).

I mean really Yabby for somebody who sneers about some gullible person taking things at face value based on what your told, and refusing to look into the deeper issues, you are doing a very good job of living up to it yourself.
