Forgery is used by some governments and non-state actors as a tool of covert operation, disinformation and black propaganda. Letters, currency, speeches, documents, and literature are all falsified as a means to subvert a government's political, military or economic assets. Forgeries are designed to attribute a false intention and aspirations on the intended target. They force the targeted government to spend a large amount of resources to refute the forgery. Forgeries are an effective tool because of their ability to hold influence even after being proven false.[1]
