How do you know that? How do you know that God isn't using islam to judge America for its heinous sins? It wouldn't be the first time God has judged a nation, would it? God used the evil empires of Assyria and Nebuchadnezzar to judge a wayward Israel. Why is America special? America has kicked God out of the public square, is the biggest propagator of pornography and weapons of war in the world, the biggest killer of unborn babies (next to China maybe), and the American people are mostly moral relativist. Now, there's a nation God can love, eh?
However, all this notwithstanding, Western Civilization is the greatest accumulation of wisdom ever to grace the earth. The concepts of human rights, liberty, equality, the pursuit of happiness, equal protection under the law, constitutional government, representative government, and so much more are gifts from God. Western Civilization is worth defending and preserving, despite the way it is perverted by some people.
By contrast, the benighted and misguided beliefs of fanatical Islamists cannot compare to Western Civilization. The hideous and barbaric shariah cannot be compared to the law that has evolved in the Western Republics. The tyrranical, talibanesque Islamic theocracies cannot be compared to Western nations. The West has rid the world of smallpox; fanatical Islam threatens to reintroduce it.
Yes. God is with us.
However, there is a caveat. "Liberalism", which is decadence and which is responsible for the sleaze and evil that have perverted much in the West, is the greatest threat to Western Civilization, greater than any foreign enemy. In fact, it is the enabler of foreign enemies. If it were not for "Liberalism", the United States would not have been perceived as decadent and weak; America's enemies would not therefore have been tempted to act; and the September 11 attack would not have occurred.
If the United States remains resolute and if the American people return to the values that made the U.S. the greatest nation the world has ever known, no foreign enemy can destroy us.
If the American people allow "Liberalism" to control them, the United States will fall because of corruption within.
