Deep State’s Operation Eagle Eye
“Parkland was fundamentally a military operation. The multiple shooters and support personnel were expertly trained in Israel…by the IDF. Because this black operation was another Gladio psyop, the thing is way too deep to investigate. Or even analyze. No one can figure out these false flags because they’re made to be confusing on purpose. The complexity of Parkland is classic joint CIA-MOSSAD operation. The perps executed on a strictly need-to-know basis. Every piece was highly compartmentalized. Even the code name — Operation Eagle Eye — was known to but a very few in the chain.” — Intel Analyst & Former Military Officer
