Fifteen years ago, Ronald Reagan was laid to rest. The 40th president of the United States had Alzheimer’s, which he made public in 1994, and died at 93. Former heads of state attended the services for Reagan, who helped bring down the Iron Curtain and eventually end the Cold War. Among the guests were former British Prime Minister Margaret Thatcher, Prince Charles and former Soviet Union leader Mikhail Gorbachev. Inside Edition’s Deborah Norville also attended with her friend Joan Rivers.
