Trump actually has put more sanctions on Russia than Obama did. To battle Russian aggression against the Ukraine, Obama gave the Ukraine blankets and MREs. Trump gave the Ukraine Javelin missiles, the best anti-tank weapon in the world today. China and Iran are trying to interfere on behalf of Biden because they know they can push him around. Russia is being Russia, and they are just trying to cause confusion. They have said they prefer Biden because they know they can intimidate him.
