Don’t buy it. What Islamic country produces anything of value other than oil? The country that really could take over is China. If they were to truly capitulate to capitalism they would pass the US in GDP in short order but they’re still married to communism.
Yeah, China for me too. The worse case scenario during our lifetimes is that the US elite joins forces with the Chinese Communist party and People's Liberation Army to divide up the world. Still, despite advances, the Chinese have somewhere to go to catch up with the US militarily ie they've only started work on their first nuclear powered aircraft carrier - a ship type the US has operated since the 60's and of which they currently operate 10.
Muslims ,though useful as pawns by the great powers, have never been a force in the world ,since the fall and dismemberment of the Ottoman Empire after World War I - maybe even earlier.
Particularly, worth noting, that since America's complete abandonment of the gold standard(1973) and the 1973 oil crisis,the US financial system has been backed by the petro-dollar. Here the US bought oil from the Arabs and in turn the Arabs reinvested the money into US bonds and the US economy. Indeed,it's the biggest protection racket in the history of the world. This to me more than anything signals the relative powerless of Muslims.
https://en.wikipedia.org/wiki/Petrodollar_recycling#1974%E2%80%931981_surgeThe whole sequence of events during that time has always been sold to the general public as the Muslim Gulf Arabs,lead by Saudi Arabia, ultimately calling the shots to the US, by placing an oil embargo ,due to their anger at America's support of Israel ,during the Yom Kippur War(1973). On the other hand, the actual long-term economic facts indicates those actions to be pure theatre.
