We know Antifa and ISIS have had a cozy relationship and that some Antifa people have been trained by ISIS.
Just like the RAF (Red Army Faction Marxist revolutionaries, look it up) was trained by PLO/Hezbollah warriors in the middle east.
What would stop ISIS and other terrorist organizations bent on destroying our way of life from providing and smuggling weapons caches through our lax left coast ports?
Horror scenario that keeps bothering me.
