yes we will have WW3 pretty much. Mowing down even 5+ civilians just to keep " secrets" sounds bad enough but from an unrealistic standpoint of *two million* people marching in together and most being shot down or killed by landmines? Whole country will revolt.
It can even just be one person to stir the fire. I wonder if there's going to be someone brave enough to try to run directly past the (most likely) guards assigned to politely intercept the mob. Will they shoot him down and will someone try to challenge that?
