God isn't disgusted with America.
Satan has gotten into the hearts of our leaders. America is failing because we have people running the show that do not care about americans, they do not care about American morals and standards and values and pride, they do not care about anything except their own money and power. Money, power, greed, selfishness, apathy, hatred is in there hearts because they opened themselves up to it.
Because of that they only serve only themselves. They would let the whole country sink as long as it's nice in their backyard.
But in a sense I'm sure God is disgusted with them for doing what they do to us, and probably disgusted with us for letting them do it.
But God isn't destroying our country. Our leaders are because they unknowingly are tempted by Satan, and gave in.
