Iran’s President Hassan Rouhani criticized dealings with US on Thursday saying the talks with Washington are “useless.” 

His comment came in a speech in Tehran during the unveiling of the Bavar-373, a long-range surface-to-air missile system that he said was an improvement to the Russian S-300.

“Now that our enemies do not accept logic, we cannot respond with logic,” Rouhani noted in the televised speech.

“When the enemy launches a missile against us, we cannot give a speech and say: ‘Mr. Rocket, please do not hit our country and our innocent people. Rocket-launching sir, if you can please hit a button and self-destroy the missile in the air’,” Rouhani said.

On Wednesday, Iran’s state TV reported that the Bavar-373 is able to recognize up to 100 targets at a same time and confront them with six different weapons.

“With this long-range air defense system, we can detect ... targets or planes at more than 300 km (190 miles), lock it at about 250 km, and destroy it at 200 km,” Defense Minister Amir Hatami told the state television.

Since 1992, Iran has developed a homegrown defense industry that has produced light and heavy weapons ranging from mortars and torpedoes to tanks and submarines, the Associated Press reported.

US sanctions were imposed again on Iran after Washington’s administration pulled out of the nuclear deal over concerns about Iran's missile program and regional influence.

President Donald Trump argued that the accord did not limit Iran’s ballistic missile program.
