In addition, there is the part of my, above, post that you didn't quote. It talks about freedom for all people... how Americans can regain freedom from their own government that they seem to have lost. God wants freedom for people, just because that's the way He is. He would like freedom for all people so that they might spread His Word. But He offers the freedom even if they don't do His work. America has freedom built into her founding documents. Because of this simple fact alone, God favors America.
The points listed in this post are just the beginnings of why God might continue to maintain freedom in America, even though many of the people of America are sinning much.

Lol. America likes to portray itself as free and freedom loving but but there's nothing free about it and the idea of America is just a colossal hypocrite and contradiction. Land of the free but spying on its citizens and the rest of the world? Land of the free but lock up more people than any other nation and most of them for petty drug offenses? Land of the free but will evade your country whenever it feels like it? Land of the free but is a country that is founded on genocide and theft? I don't think so. America is a delusion and so is anyone who think it's the greatest country or the country of god etc and this is exactly what's wrong with both blind belief in religion and blind patriotism.
