"They are reactionary people and want to return to the era of the presidency of crazy Bush. Bush made his utmost efforts to attack Iran but he couldn’t," Firouzabadi told reporters on the sidelines of the annual nationwide parades at the mausoleum of the Founder of the Islamic Republic, the Late Imam Khomeini, South of Tehran on Tuesday morning.

Stressing that Republicans' attempts to continue the path of Bush to trigger war against Iran are futile too, he said, "War will also fail to produce any result for them because Republicans are only chanting empty words and slogans."

Firouzabadi, meantime, underlined Iran's determination to fight against the arrogant powers, and said the terrorist groups in the region are the fingertips of the world powers and Iran will stand against them too.

"All the regional countries should know that the US, Israel and Britain are supporting the terrorists," he added.

In relevant remarks in August, Chief of Staff of the Iranian Armed Forces Major General Hassan Firouzabadi expressed confidence about the imminent defeat of ISIL and other terrorist groups, and said they will have no place in future developments in the region.

Also, in February, Islamic Revolution Guards Corps (IRGC) Quds Force Commander Major General Qassem Soleimani underlined that the terrorist groups in the region, specially the ISIL, are experiencing the last days of their lives.

"Given the heavy failures that the ISIL and other terrorist groups in Iraq and Syria have sustained, we are sure that these groups are nearing the end of their life," Soleimani said.

He said that persuading and organizing the Takfiri streams to impair the face of Islam and creating sedition and civil war among Muslims is the last weapon used by the arrogant powers.

Also, in October, General Soleimani underlined that the US moves in the region and the terrorist attacks by the ISIL would end in failure.

"I believe that both the US moves and the terrorist acts of the ISIL are doomed to failure because they are not in quest for truth," General Soleimani told reporters in Tehran.

"Their solution will not lead to victory; we have all witnessed in Syria that the measures they adopted did not produce any fruit (for them)," he added.

General Soleimani underlined that the victories gained by Islam and the Islamic Republic of Iran had all been the result of their real quest for truth. FNA reported.
