Was the american revolution a radical revolution? explain why or why not

Especially since the early 1950s, America has been concerned with opposing revolutions throughout the world; in the process, it has generated a historiography that denies its own revolutionary past. This neoconservative view of the American Revolution, echoing the reactionary writer in the pay of the Austrian and English governments of the early nineteenth century, Friedrich von Gentz, tries to isolate the American Revolution from all the revolutions in the western world that preceded it and followed it. The American Revolution, this view holds, was unique; it alone of all modern revolutions was not really revolutionary; instead, it was moderate, conservative, dedicated only to preserving existing institutions from British aggrandizement. Furthermore, like all else in America, it was marvelously harmonious and consensual. Unlike the wicked French and other revolutions in Europe, the American Revolution, then, did not upset or change anything. It was therefore not really a revolution at all; certainly, it was not radical.
