Sudden Jihad Syndrome
Main article: Sudden Jihad Syndrome
"Sudden Jihad Syndrome" is a term Pipes coined to describe Muslims that suddenly or unexpectedly turn against civilized, Western society and engage in acts of terror. Pipes has argued that due to this alleged phenomenon all Islamists must be considered potential terrorists.
- "...a widespread pattern of Muslims who lead quiet lives before turning to terrorism" 
- "Individual Islamists may appear law-abiding and reasonable, but they are part of a totalitarian movement, and as such, all must be considered potential killers."
