Reagan is revered as a Liberator in Eastern Europe; the only people who hate him are former Politburo members and our low Information Commie Wannabe Progressives
Your concern for Europe is very touching but I'm more interested in my own country.
Reaga was one of the most corrupt, most crooked presidents. Made the US into a debtor nation. Brought our health care system to ruin. We will never get out from under the damage he did. Raised taxes 11 times on the working class, cut taxes for the wealthy, 11% unemployment (5.4 under Obama), tripled the fed deficit (Obama has cut it by 3/4ths). Reagan was a good prez for the 1% but almost everything he did harmed the country and the working class.
The well-meaning Socialist EMTALA was a disaster that wiped out many hospitals, trauma and burn centers and continues to cost the tax payers more than it was ever worth.
By any standard, Ronnie Ray-Gun and his astroligers were a disaster for the country.
OP needs to brush up on history. Gorby did not tear down the wall because Ronnie told him to. Reagan did do one thing right - he started the treaty that Obama brought to fruition. Reagan was most certainly in favor of gun control.
