Apparently, because God has blessed us more than any other nation... LMAO... Take THAT England...
"Many of our founding fathers recognized that God is the one true God. On our coins we read, "In God We Trust." In our pledge we say we are "one nation under God." And in our national hymn we sing (pray), "God bless America." Our Founding Fathers also created a government based on God's moral law as found in the Ten Commandments. In the Bible we read, "Righteousness exalts a nation (Proverbs 14:34)." And in Psalm 33:12 we read, "Blessed is the nation whose God is the LORD." The principles contained in these passages are universal in their application to any individual or nation that would choose to believe in the one true God and live according to his moral absolutes. Toward this end it seems that God has blessed America perhaps more than many countries in the world. "
