"What part of, 'about that day or hour no one knows', are you not getting?" - God

Speculation is endless, and perhaps inevitable, that the End Times are upon us.  This is nothing new, the history of the Church is full of "signs" and "portends" that were sure signs that the end was nigh.  Yet here we are, the world goes on and so does the Church.  American Evangelicals, in particular, seem to be infected with the notion that things happening in our world today, and in our country in particular, are signs of the decline that they are sure must happen if their interpretation of prophecy is about to be fulfilled (A Pre-Tribulation, Pre-Millenial, Rapture is typically viewed as happening AFTER a steep and momentous decline of the Church and society).  This pessimism is an easily self-fulfilling prophecy, as there will always be more bad news than good news in the news.
Many of those who are convinced that they see the signs are the same people obsessed with taking the Bible "literally", which of course nobody does because it is full of metaphors and hyperboles, along with figurative language like poetry and proverbs.  Not to be side-tracked by the issue of Biblical interpretation, but why won't they take God "literally" when Jesus said that ONLY the Father knows when the End will come.  Jesus doesn't know, the angels in heaven don't know, so why do you think that you've somehow cracked the code and now you see that the latest earthquake or terrorist attack was a "sign" from God?
A related issue is the American overvaluation of him/herself in the will of God.  When something bad happens here, in our society or our Church, it seems bigger, more important, than what is happening in Christ's Church in Africa, South America, or Asia.  If the American Church shriveled to nothing (not something I see happening, but let's look at the worst case), but the Third World Church doubled, would Christ's Church be growing or shrinking?  Would that be a sign that the End is near, or that the Spirit of God was moving in power among his people?  Western, affluent, white, souls aren't worth any more to God than Eastern, poor, dark skinned ones.  Many American Christians would never say that they think that, they probably don't even consciously think it, but it is reflected in their insistence that a setback in the Church here is so important that it must be a sign.
Are you aware that violent crime in America is now at its lowest rate since the 1970's?  This is a decades long trend, and is matched by an ever lower trending abortion rate.  The Supreme Court ruled that same sex marriage was a right.  Which of those three facts are being touted by the pessimist that insists that America is over, Facism is around the corner, and the Anti-Christ is waiting in the wings?  The search for signs is a waste of time, and shows a lack of trust in the will of God, but even if it wasn't, why are the negative signs important but the positive ones ignored?
It has been suggested that American Christians will soon be faced with a dilemma much like that of Dietrich Bonhoeffer in Nazi Germany in the late 1930's.  Unfortunately for those hoping for hysteria, the historical parallels between America in the 2010's and Germany in the 1930's are non-existent.  They had a state sponsored/run Church, our Church is independent.  They had a police/military that was willing to follow a Facist path and attack its own people, we do not.  They had an infant Republic that was easily replaced by a dictator who voted in his own "emergency" powers, we have a 200+ old Republic that has survived the Civil War, the Great Depression, and WWII.  There are Christians in many countries in the world today facing persecution on a level that Bonhoeffer would have recognized, Americans are not among them; for that we must continue to be thankful to our Father, when he's ready, he'll send his Son back, and like he said, it'll be a surprise.
