Stephen Walt views states fearing not from their most powerful enemies but from their most threatening enemies and, therefore, seek to attain balance against them. As he believes, the very feeling of threat is a function of four agents of compressed power of a country. These agents include threatening agent, power of invasion, intension of using this power and being geographically near to the source of threat. On this basis, IRI has regarded what happening in Syria as a threat against its own security and, therefore, intended to defend and support the ruling state of Syria directly. It should, however, be stated that IRI`s only reason for the defense and support is not what is said in Walt`s theory, rather, supporting resistance pivot and necessity for IRI role-playing in it with regard to its right-seeking ideals may be known as the main reason in the field. In this way, IRI intends to support and protect its regional united nations.
