If Islamist terror is due to Western imperialism, why isn’t South America and Sub-Saharan Africa pumping terrorists into the world?

Again I hear talk everywhere that Islamist terrorism is a reaction to Western imperialism.  It’s supposedly got nothing to do with radical Islamists.  I have to wonder if why Korea and Vietnam didn't start pumping terrorists into the world as an aftermath of the horrendous wars there, why oil producers in South America and Sub-Saharan Africa didn't start pumping terrorists into the world in reaction to western meddling there.

The world didn't know of jihad till after WWII when it became evident that future security of states would henceforth depend on the security of their oil supplies, whether to power their economies or to fuel their militaries. There is oil all over the world and there has been competition and conflict to secure that oil, but only the oil of the Middle East drives global terrorism. The cause is Saudi Arabia, which has used its oil revenues to drive fundamentalist radicalization of Muslim societies all over the world, infesting them with mosques and seminaries that disseminate Saudi scripted fundamentalist, hateful perspectives. Every major Muslim terrorist organization in the world is connected to a web in the center of which sits Saudi Arabia. This social re-engineering and radicalization of Muslim societies by the  gold-laden, oil-drunk Wahabbis is so successful that even the liberals of the West run to blame their own governments entirely for the rise and spread of Islamist terrorism.

So many Muslims died in the Iran/Iraq war, but the slaughter of Muslims by Muslims is never mentioned by the Chomskyites. They go straight to, and only to, the American involvement...
