Yes. Trump said yesterday his mother and sister, who were in the house, had to know. Makes you wonder how many American born Muslims feel the same way?
Safe bet: 100%
I have worked with muzz, most of whom, by the way, were Americans; and I can tell you a lot of them had a visceral hatred of Israel.
Mao (in)famously wrote in On Guerilla Warfare (1937):
Many people think it impossible for guerrillas to exist for long in the enemy’s rear. Such a belief reveals lack of comprehension of the relationship that should exist between the people and the troops. The former may be likened to water the latter to the fish who inhabit it. How may it be said that these two cannot exist together?
This is usually aphorized as “The people are the sea that the revolutionary swims in,” or an equivalent.
I think this is exactly the same for the jihadi and the larger muslim community.
