Dehqan, a brigadier general, referred to Netanyahu's comments at the U.N. General Assembly this week.
"Israel will not allow Iran to get nuclear weapons," Netanyahu said. "If Israel is forced to stand alone, Israel will stand alone."
Dehqan said the Israeli government is too weak to take any sort of unilateral action against Iran.
He characterized Netanyahu's comments as "warmongering" and "aggressive," state-funded broadcaster Press TV reported Friday.
The International Atomic Energy Agency said this year it believed there was a military dimension to certain aspects of Iran's nuclear program.
Iran maintains it has the right to a peaceful nuclear program as a party to the Nuclear Non-proliferation Treaty.
U.S. President Barack Obama said he respected that right as long as Iran provided assurances it wasn't seeking a nuclear weapon.
Iranian President Hassan Rouhani said his administration is opposed to a weapons program.
