Or consider this scenario…
Putin calls Biden and tells him that if the United States intervenes, Burisma will be nationalized or acquired by the Russian Federation. All assets of foreign nationals will be considered property of Russian Federation.
Or, Biden can do what Putin orders him to do. That is to stay out of Putin's way. As payment for doing absolutely nothing, Biden family may keep their holdings in Burisma, have exclusive energy contracts into all of Europe, and become multi billionaires….everyone wins. Everyone except the United States tax payer, who once again, will watch their leaders sell them out to the highest bidder.
