Insisting that boosting Iran’s military power is for peaceful purposes, the Islamic Republic’s President Hassan Rouhani warned the “enemies” on Tuesday that any military action against the country will be costly.

“Iran’s military power is meant for defense, but any hostile move against it would cost the aggressors dearly,” so-called moderate mid-ranking cleric cautioned.

Rouhani, who was speaking to a group of defense ministry officials said, “History has taught Iran to grow stronger and insist on pursuing its goals, otherwise other countries would try to bring Iran to its knees.”

The Iranian president made the remarks in a ceremony marking the National Day of Defense Industry. The event also featured the unveiling of the latest achievements in the defense sector, including the first homegrown fighter/trainer jet “Kosar” which presumably underwent its successful flight-tests today in the presence of President Rouhani, according to state-run Mehr News Agency (MNA).

Referring directly to Washington, Rouhani claimed that the reason behind keeping US back from launching a military attack against Iran is the Islamic Republic's defense capabilities.

"They know that attacking Iran would have great consequences for the U.S.,” Rouhani said.

Rouhani praised the “existing unity among the Iranian people, leadership and the armed forces,” while he had earlier repeatedly accused the Islamic Revolution Guards Corps (IRGC) of meddling in his government’s affairs.

During his second presidential campaign in May 2017, Rouhani bitterly criticized IRGC for attempting to abort his Administrations efforts toward achieving a nuclear deal with world powers.

He singled out an incident where IRGC publicly displayed missiles with the sign 'Death to Israel' in Hebrew attached to them.

The cleric turned politician went even further by describing IRGC as an armed institute interfering in Iran’s economy where the private sector dares not to compete with it.
