Well, there are definitely more ways than one to fight a war. You have drones, espionage, and economic agreements between countries to spite an enemy country and hurt their industry. Another weapon in the arsenal of economics is the economic sanction. Now, espionage and these economic agreements/sanctions (in the form of embargoes, for example) have nearly always existed in past conflicts, but now they are more sophisticated and complex. Espionage has turned into cyber espionage, followed by the development of highly advanced and technological weapons. I think there is such a thing as traditional war-it's a direct engagement with two opposing sides on a battlefield, all the spying and economic punishment just the addition to the actual war. Basically, not a full on conflict, but maybe the things leading up to that conflict. The war we fight today is mostly through economics, the overthrow of governments both illegally and legally (often under covert measures by unknown agents) and establishment of new ones, proxy wars and cyber espionage. War will never be fought the same way again, especially as our methods advance and expand to draw the conflict out. Most countries are guilty of these methods.
