The common sentiment among the vast majority of Americans during World Wars I and II was isolationist, and anti-war. The bombing of Pearl Harbor and the sinking of the Lusitania ship were shocking, tragic stories, used as an excuse to drag Americans into fighting against the Germans. Little details are forgotten, such as the fact that F.D. Roosevelt had already cut the Japanese oil supply (which is virtually an act of war) and was helping England build war airplanes in Canada during WWII. Also, the Lusitania was carrying munitions, and thus a legitimate target for the German U-boats.
Likewise, the terror attacks of September 11, 2001 were a great gift for the neo-Conservatives who wanted to invade Iraq and Afghanistan, lining the pockets of those who profit from war, and it was a boon for the government in that it enabled the hurried passing of the Patriot Act. Dylan Roof’s shootings were used as a pretext to start attacking anything which symbolizes Dixie. Charlottesville 2017 was used as a pretext to attack free speech on Facebook and Twitter, and it was a pretext for censoring websites such as dailystormer and infowars. Finally, this last shooting on Saturday, October 27, 2018, at a Pittsburgh synagogue, is being used to attack gab.ai, one of the important viable alternatives to the big three, Google (which owns YouTube,) Facebook, and Twitter, because the shooter had a gab account. We have yet to see if it will be used as a pretext for anything else. Likewise, there may be a “tragedy” which happens with the caravans coming up through Mexico.
There are other examples, such as the Nikolas Cruz shooting in Florida which was used to try to push gun control.
I don’t care to speculate on false flagging (This guy is good for that https://youtu.be/tpI0c1fKXW4 ) but whether false flag or not, recognize the pattern. Something bad happens, the government and corporations use it as an excuse to push their own agenda. It’s been going on for a long time.
