ISLAM PLANS TO DESTROY WESTERN CIVILISATION "FROM WITHIN"

i got a pretty good grasp of history but i still cant seem to figure out when the jihad stopped. i mean temporarily. like just before ww1 their weren't muzzies attacking our fucking boats. and their is some vague fucking "colonialism" but we didn't butcher them. when we had the chance. when did it slow down? all i got for that period is just a big blurry blind spot.
