There is nothing to prevent the peoples of Austria, Hungary and Bohemia and Moravia from changing their constitutions and bringing back Hapsburgs. I believe Otto von Hapsburg is or was a European parliamentarian. Since they don't chose to do that, you will have to impose your autocratic monarchy by force, apparently in the name of Metternichian "legitimacy". That is the opposite of Burkean conservatism, which allows for organic and incremental development and proscription. The peoples of Mitteleuropa are free to chose their own destiny. And all you can do is rail at Wilson (and presumably Reagan, since obviously the formerly Communist nations have only recently become free and democratic once again) for helping them have the freedom to do so.
Woodrow Wilson was the worst American president in history. His completely unjustified intervention in World War I, which tragically destroyed the German and Austro-Hungarian monarchies, helped pave the way for Nazism and the spread of Communism. There are few historical figures that I hate as passionately as Wilson, and I cannot take seriously any "conservative" who does not recognize how evil his influence was.
It was Wilson whose "make the world safe for democracy" philosophy was the opposite of Burkean conservatism, not those of us who hope to reverse the terrible damage he did.
Obviously, the people of central Europe have to be convinced that the Habsburgs should be restored. When I said that I favor restoration this is what I meant. There are organizations working to achieve this goal by peaceful and legal means, and I support them. A monarchy imposed by force would not last very long.
