Reagan’s son, Michael Reagan, offered this advice for Obama on the Townhall.com website:
"I suggest that President Obama might want to study how Ronald Reagan defeated the Soviet Union.
"He did it without firing a shot, as we know, but he had a super weapon -- oil.
"Oil was the only thing the Soviets had in the 1980s that anyone in the rest of the world wanted to buy, besides ICBMs and H-bombs, and they weren't for sale.
"Since selling oil was the source of the Kremlin's wealth, my father got the Saudis to flood the market with cheap oil.
"Lower oil prices devalued the ruble, causing the USSR to go bankrupt, which led to perestroika and Mikhail Gorbachev and the collapse of the Soviet Empire."
