WASHINGTON — Iran is wrapping up two months of its most intense military exercises in decades as it tries to deter potential attacks from its archrivals Israel and the United States, security researchers tell VOA. The Washington-based researchers also say the Iranian drills that began in late December, and were due to conclude by mid-March, have involved some weapons systems that pose a threat to the U.S. and Israel and others that expose weaknesses in Iran’s deterrent capabilities. “The pace, intensity and publicity of the exercises is unprecedented,” said Behnam Ben Taleblu of the Foundation for Defense of Democracies.
