TEHRAN -- Two top Iranian Army commanders have visited a key airbase in the southeastern part of the country amid heightened tensions with the United States.
Deputy Commander of the Iranian Army Brigadier General Muhammad Hussein Dadras and Brigadier General Hamid Vahedi, commander of the Iranian Air Force, toured Shahid Del Hamed Airbase in Chabahar in Sistan and Baluchestan province. 
The two commanders evaluated the base’s combat capability during their visit.
Brigadier General Ahmad Reza Pourdastan, head of the Strategic Studies Center of Iran’s Army, said the armed forces are ready to give a “crushing and regret-inducing” response to any “stupid” act by the enemy.
Pourdastan made the comment in response to the United States’ threats against Tehran, which he said “are not a new matter.”
“We monitor all threats in the region and beyond and will accordingly develop the necessary defensive and offensive capabilities within ourselves,” he said.
He said the U.S. has been threatening Iran since the victory of the 1979 Islamic Revolution, and therefore, Tehran is not worried about such threats.
He reaffirmed the total readiness of the “invincible” Iranian Armed Forces to counter enemies backed by the nation.
“The Americans are well aware that if they intend to carry out any act of aggression, they will receive a far heavier and more regret-inducing blow,” Pourdastan asserted.
The top Army commander said U.S. threats do not stem from power and capability, but rather from its weakness.
On March 30, Trump threatened Tehran with military action if it refuses to hold talks with Washington over its civilian nuclear program.
