Typically aging "American Prophets" see their own mortality creeping up on them and since they don't want to believe they will die before what they've promoted comes to pass, they begin to see signs of their prophecy being fulfilled in anything and everything. Americans in general also tend to equate what's happening in this country with what's happening in the entire world.
Each apostate American is being replaced by multiple faithful believers elsewhere and this author is just another run of the mill aging "American Prophet" who as dusk settles around him can't see the forest for the trees.
