Labeling a foreign government's military as "terrorists."
If there is a better way to discredit the entire fiasco called the "War on Terror" once and for all, I cannot think of it. If you start calling military forces of other countries "terrorist" organizations because you claim you have a beef with them, it is also the best way to discredit the entire United States with the world for good.
You could not sit down at a table and form a strategy more effective at alienating the entire world from the U.S. and assuring them the only thing that Amerikwa will ever be able to comprehend is brute force delivered swiftly, mercilessly and without apology. Most of the other nations are already beginning to think of the coming Third World War as a necessary step in the history of the planet that cannot be evaded or circumvented because of Amerikwa's belligerence and abandonment of diplomacy as a tool to achieve it's goals.
Try to visualize what is going to happen now. Russia and China are going to continue doing honest business with Iran. That means Russia and China are going to be labeled collaborators. Amerikwa gives them no options. By simply buying and selling with this sovereign foreign nation, they have to choose sides. That's really, really dumb policy.
Itz coming and thatz a given.
