In a piece written for The Cipher Brief, Michael Eisenstadt of the Washington Institute details Iran’s weapon of choice for imposing its will on domestic and foreign threats alike — cyber attacks.

Eisenstadt, as well as experts contacted by Business Insider, say that Iran has a weak conventional military that couldn’t possibly hope to push around stronger countries. For that reason, cyber attacks represent the perfect weapon.

Cyber attacks are cheap, ambiguous, hard to pin on any one actor, and almost completely without precedent when it comes to gauging a military response.
