"Constitutional monarchies, through their structure, avoid those four republican perils: excessive rigidity, as in the American system, which is reduced to near paralysis whenever the President is seriously threatened with impeachment; political conflict and competition between the Head of State, Prime Minister and Ministers, a hallmark of the French Fifth Republic (an inherently unstable model curiously followed in a number of countries); extreme instability, which often haunted the Latin versions of Westminster; and regular resort to the rule of the street to solve conflict, which permeates those systems which live under the shadow of the French revolution."
