no smiley face there so I'm assuming yr serious... so, just to let you understand our perspective, us yanks see it the other way around. we offer a watered-down version of the pomp and ceremony your "royals" made famous.
Your military funerals are something else in terms of intensity. You have turned the POTUS into a semi-divine being, next to whom QE2 must feel underdone. The difference is that the POTUS functions in the real world (even if their sense of reality can be doubted by many) while QE2 is rolled out for ceremonial occasions and otherwise left to her own amusements.
A lot of pageantry can be form with no substance and signs and symbols with meaning only discernible to a few. But see then more potent US rituals as being direct and unambiguous - very accessible - more democratic.
