In what world is Russia a regional power? Russia is by any standard a global power.
Russia has the world's 6th largest economy by PPP. It has the biggest nuclear arsenal in the world. The second most powerful military in the world. The most powerful land army in the world. A blue water navy. Russia's extensive mineral and energy resources are the world's largest, and it is one of the leading producers of oil and natural gas globally. A member of the G-20.
Even americans agree China is far more militarilly stronger than Russia. Id place Russia number 3 followed by Israel, Japan, France, Uk, Pakistan, India, Turkey, South korea.
