>Or do they just leave reddit and come to /pol/ when shit goes down?
yep, pretty obvious going off their pre-approved images and post structures. It‘s nothing new though and not unique to the US or Israel, the same could be observed with every cyber capable country getting temporary exposure in relation to Syria, one time the Brits raided the thread for about three days altough I don‘t remember the reason for that, then you had the Turks during the Russian Jet shootdown, and again during their invasion into Syria. The US-reddit raids became a common reoccurrance ever since last years Apeil Strikes and peaked after this years April strikes though they were so similar in method and rhetoric you couldn‘t tell them apart in the archive. And since around mid last year the JIDF kikes themself have begun to shill their dumb narrative in here everytime their side chimps out in Syria. 
On the bright side the Rebel shills are pretty much gone at this point.
