oh come on you can't be that dense.
Extremism in the Middle East pre-date any USA involvement. It actually dates back to WW1 when *ahem* the British Empire screwed over the Arabs after the defeat of the Ottoman Empire. And worse after WW2. Nazi'ism never ended with the defeat of Germany in 1945 it continued in the Arab world under the Baath party.
I know it predates USA involvement. I know full well what the British (and French) did to the region. What with BP, with the regiments of Palestinians fighting for the cause, the destruction of ships meant to ferry hundreds of thousands of displaced Jews (later Israelis) to the region, the destabilization of the Ottoman Empire, the Afghanistan wars, the establishment of borders across the Duvant line, the rebellion of the Parthans. I know well.
All I am saying is that the problem of extremism met new heights when America's killing of the Muslims in that region hit new numbers of casualties, when America's involvement in the Russian Afghanistan war ended and they turned their backs on the Mujahideen, to many people ''corrupted Saudi Arabia's government'' and double dealt with the Shah, Saddam Hussein and others.
It's really not hard to see, or imagine, that in a couple of countries where America and NATO are responsible for; over a million civilian deaths due to war itself (bombs and bullets); poverty; destruction of important infastructure like water lines and electricity plants; inflation; and Westernization against the cultural norms, that those afflicted would seek some form of retribution, whether motivated by personal loss, nationalism, or just extremism.
The issue, I find, is that as soon as the word ''extremism'' or ''terrorist'' is thrown out, then there is no argument to be made, sort of like the word ''heresy'' back in the days where the churches ruled the lands. When you really think about it though, what is terrorism?
The word was coined in France under the government's ''Reign of Terror'', and it originally applied to governments who intimidated through fear. It is defined as ''the use of violence and intimidation in pursuit of political aims'', and under that definition, both Britain and the US are guilty of killing more people through terrorism than the Muslim extremists are.
