By far the largest national supplier to ISIS is .... who?
Morocco.
15,000 Moroccans are part of ISIS. No wonder France, with its ancestral ties to Morocco, has a problem - on top of the hundreds of its own people. A number of the murderers in the recent rampage were French/Belgian of Moroccan descent.
Number two is Tunisia with 3,000.
Old buddy Saudi Arabia is in third with 2,500.
Which you'd never know by reading the Western press.

Why Morocco?
No idea.
Another peculiar fact. There's very little, if any, terrorism in Morocco itself.
