It'll get to the point when the living Jihadists will start to realize *everyone* that they knew as young wannabe terrorists were killed by "the great Satan" ( nations that will not tolerate Islamic murder ). Kinda saps one's motivation when the enemy keeps wasting your people while "God is directing your leadership..."
It's just like living JWs that have ALL seen their older family, friends, congregation elders and former bible teachers/students die off when the end was supposed to have come by now.
Don't wait too long to leave the Watchtower. Finding out your doubts were real when it's too late in life to start over is a very painful feeling.
