"When we look at the Russian-Ukrainian conflict, we can pay attention to all the others. It's been 20 years since the illegal war in Iraq that killed millions of civilians — when will [former U.S. President George] Bush and (former British Prime Minister Tony) Blair be arrested?" he wrote on Twitter.

Wallace stressed that everyone who commits a war crime must be brought to justice.

Earlier, the US military Noctis Draven called on mercenaries from the United States not to take part in the conflict in Ukraine on the side of the Ukrainian army.

Draven also expressed confidence that Ukrainian servicemen should lay down their arms or go over to the side of Russia.

According to the former adviser to the head of the Pentagon, Douglas McGregor, the CIA sends American servicemen under the guise of contractors to Ukraine to help the Ukrainian army in managing equipment supplied by NATO countries.
