Christian Apologetics (https://en.wikipedia.org/wiki/Christian_apologetics)
One of the Christian Arguments claims that America was founded as a Christian nation.
Things are a bit different here in Australia. I fact one of our Prime Ministers (Bob Hawke) declared himself to be an agnostic and still managed to retain a 72% approval rating - and went on to win another three elections.
Sadly, our current Prime Minister (Kevin Rudd) is an Anglican Christian with a tendency towards Creationism and many in his cabinet have similar beliefs, so I guess it won't be long before "secular" Australia becomes as "christianised" as America.
