Perhaps that's because none of those countries are the greatest nation in the history of the planet.
We certainly started off that way... One Nation Under God, the greatest nation in the history of the world. Unfortunately the socialists & new world order bigots & hate God crowd & hate America crowd, & demoRATs & RINOs have done everything they can to destroy America and turn it into 0dumb0's personal Zimbabwe.
Even with the sordid, bloody history of communism & oppression, unfortunately Russia & China probably have a greater percentage of their people who feel strongly about their country, than we do here in the U.S. If these countries don't feel compelled to dip their flags, why do we have apologists in the USOC who feel compelled to dip our flag. A sad indictment for what USED to be the greatest nation in the world.
Meaning no disrespect, do you have another one in mind? I don't let Baraq al-Husayn bin Obama define my country for me.
