Impose Oil Embargo on President Putin's Regime in Russia and make him respect International Law

The World has been changed and thrown back to the periods of Cold War since Vladimir Putin has taken his 3rd presidential term. Before that there was a terrible War in Georgia held by Russian Army. Few years later he annexed Crimea. Now the proxy war extended towards Donetsk and Lugansk regions of Ukraine. Probably this would lead to a frozen conflict like with Russian troops in Moldova. Every day of such proxy war requires a big investments for Putin's Regime.
The main source of such aggressive Russian Foreign Policy is its Gas and Oil sales and of course mild reaction of the World on the acts of violence. We propose to impose Oil Embargo on Russian Federation in order to cut off supply of such aggressive Foreign Policy towards neighbor countries and make Russia respect International Law.
