In Britain, the monarch is kept quite separate from the prime minister. This allows Brits to harshly criticize their chief executive without being thought unpatriotic.
When a president gets into trouble, he is inclined to wrap himself in the flag so those who challenge him are accused of being un-American and unpatriotic. Imagine how much easier it would have been to censure Richard Nixon had he not also been head of state.
