All I've see is content from sources that have a clear political motivation.
Is this an established phenomenon that has occurred throughout history, and is there any consensus that today, in 2019, there exists a global Islamic conspiracy to inflict Jihad in stages?
No conspiracy sites, please. I'd prefer something academic or with lots of supporting evidence and cross references.
David wood is very good at explaining jihad
Stages and appropriate response?
Stage 0 and 1 - Clueless/Secret Jihad - Education about real Islam - Islam's heroes on 9/11 were the ones who murdered thousands of innocents
Stage 2 - Defensive Jihad - Education with zero tolerance for criminal behavior. Muslim criminals are to be reported as muslims.
Stage 3 - Offensive Jihad - Crusade, the just war, Iraq, ISIS, Afghanistan, Laden swimming with fishes
