Only a low-information con would try and give Reagan credit for ending the cold war and bringing down the Berlin Wall. You people really need to stop spinning.
FACT: The Soviet economy had begun to stagnate by 1975 and Gorbachev recognized the fundamental weaknesses in the Soviet system years long before he took over power and years before Reagan was President. It was Gorbachev who reformed the Soviet system. Reagan merely grasped his coattail.
The Soviet economy was a lie for 70 years, but Reagan forced them into collapse by military spending that the Soviets could not match.
