Silent weapons, as the name suggests, play their part by quietly spreading chaos. Weapons of mass destruction today, are not guns or grenades; rather, they are global supply of money through privately owned reserves. Everything that is expected from an ordinary weapon can be expected from silent weapons, but the only difference is how they operate and what the consequences of such a quiet war are.
In biological warfare and quiet wars, it is more about how the minds are controlled. The government shutdown is more achievable when the people think that their government has failed and that they have no future whatsoever until the international forces intervene. It is then the elites can play their cards and take over the energy reserves of a third world country or whatever they are interested in. The media is used to manipulate the minds of the people; mental activity is sabotaged. An emotional appeal to the people always works like a charm.
