Harding, Coolidge, Hoover, or so it's said. Also the Middlewestern Republicans of the Taft-Bricker stripe in the 1930s and 1940s.
Reagan came after thirty years of Cold War. In the early years of the Cold War, Republicans were still quite skeptical of foreign involvements. And even during the Reagan era, things looked differently at the beginning than at the end. In 1979 Americans were frightened of losing everything to the Soviets. So we had to get tough. After 1989 some thought we could do anything and take on any great foreign task.
So basically, they are comparing President Bush to Republicans before WW2??? Do you feel that is a fair basis to say that he is straying from traditional republican policies?
No..go back further
Only Nixon could go to China.
