On Tuesday, Brennan told US media that Russia was playing by its own rules in Syria by pursuing a "scorched earth policy" which has claimed thousands of innocent lives. Brennan said that the United States would never act likewise during a military conflict.
"This statement by the CIA director is the last salvo in the information war waged by the Barack Obama administration against Russia. These allegations sound cynical, especially taking into account the barbaric nature of the majority of wars the US has waged," Korotchenko told RIA Novosti.
At the same time, the expert expressed hope that the new CIA head, who will be appointed by Trump in the coming days, will adhere to a more reserved public policy.
"The head of an intelligence agency should not act as a mouthpiece in an information war. At least, this is not serious," Korotchenko concluded.
Earlier, Brennan’s statement was also criticized by Franz Klintsevich, the first deputy chairman of the Defense and Security Committee of the Russian parliament's upper house.
The US has itself practiced the things Brennan accused Russia of doing, namely dropping nuclear bombs on Japan during World War II and invading Iraq, he stressed.
"Did the United States leave anything but scorched earth, which still yields terrorists, after the invasion of Iraq?" Klintsevich said.
The Russian military has assisted the Syrian Army in the majority of recent battleground events in Syria. In December, Syrian government forces backed by the Russian military liberated Aleppo. A ceasefire regime has been established in Syria and is expected to be followed by peace talks between the Syrian government and moderate opposition.
