"When Americans Believe in God, God Will Bless America"

From Huber Heights, Ohio: Today I passed a billboard on I-70 (in Indiana, I think it was) that read
WHEN AMERICANS BELIEVE IN GOD, GOD WILL BLESS AMERICA.
On the surface that’s innocuous, right? We all want God to bless America, right? But there’s a threat implied, I think. That sinners are running the country. That we’ve strayed from the path of righteousness.
Myself, I think it’s a little scary, the way the wind is blowing, based on billboards across the Heartland.
