The cyber war that exists isn’t just between the United States and Iran. In fact, most of the action is heating up in the Middle East. A newer comparable version of Stuxnet, called Flame, has ravaged countries such as Syria and Saudi Arabia as well. One of the oil giants in Saudi Arabia, called Aramco, was victim to cyber attacks by a group called The Cutting Sword of Justice. Right now no country been made in affiliation with this hacker group, but the cyber attack ended up with over 30,000 computers ruined and unimaginable amounts of data wiped from database servers. After around a week of repairs, the company was finally back online, but the damage that had already been done was irreversible.

Even representatives of countries are coming out and publicly declaring intentions with cyber security. At the beginning of last year Ali Hosseini Khamenei, the supreme leader of Iran, gave a speech to a public news agency stating to his people, “you are the cyber-war agents and such a war requires Amman-like insight and Malik Ashtar-like resistance. Get yourself ready for such war wholeheartedly.” 

The United States has not so much as publicly let their intentions known, but it’s obvious that if the US does want to keep up with this constantly changing battlefield then steps must be taken. There has been speculation as far as the extent of the US administrations policy of cyber war with other countries (shown in link below), but no official statements have been given as of yet.
