First the US unseated the Mosadegh govt. to bring in Shah and his repressive regime. Then it funded Saddam and armed Iran to fight each other, thus making enemies out of Shia Iran. Then it used Saudi conservative ideology to stop Soviet expansion towards warm water ports in Afghanistan, but there was blow back and the virus of extremism went out of control blowing up in the face of the US on 9/11.
The British and French used Arab and Turkish nationalism to break Ottomn way back and did the Sykes and Picot. The little countries created from that, most had or still have US supported autocrats. As a reaction, political Islam raised its ugly head with Afghani, Hassan Banna, Qutb, Nabhani, Moududi et al in the lead.
And now Islamophobia became a cottage industry after 9/11, painting all Muslims as "terrorist or terrorist sympathizers". Zionists and their fellow Muslim-hating Hindutva brigade have both joined hands and in some cases, Zionists led these efforts, while the clueless US public have drank this Koolaid.
So the OP is correct for the most part, but the US public is not responsible for this, it is the oligarchy and the foreign policy establishment with their stupid self defeating policies and geopolitical games, that are mostly responsible for this. US public has also been an unfortunate victim and they will not wake up, till China dethrones the US as the No. 1 power. Then the soul searching will begin, not before that.
