I used to work a desk in Medterranean, North African, and Middle Eastern intelligence for NACSECGRU. The situation in France, Spain, and Italy are a long time in coming. The time is ripe.
“...the shooter could be a Muslim jihadist, who hates Jews and regards fellow Muslims serving in the military as traitors.”
This is my opinion, too, Dagnabitt.
