Because the spiritual authority (religious leaders) has subjected itself to secular authority (government leaders) it is difficult for spiritual leaders to give secular leaders directives about what the secular leaders should be doing with respect to matters that fall under the province of secular leadership.
Consequently the spiritual leaders can't see their way clear to addressing the spiritual malaise that results, for example, from the world's addiction to oil because that sort of problem belongs squarely on the shoulders of the secular authority. Spiritual leadership has sued for secular involvement, and has been willing to give direction to secular authority, with respect to matters that properly and traditionally belonged in the church's domain like helping the poor; caring for the sick; sexual, marital mores; etc. Spiritual leaders are not accustomed to thinking and offering spiritual counsel about the largest political and most important strategic challenges the secular leadership is facing.
For starters the spiritual leadership can't imagine what a solution could even look like nor can they credit themselves with being able to think through all the complex practical ramifications of an attempt at a solution. So they keep thinking about the smaller issues and never even see the effect on the world's spiritual condition of the larger geo-political forces are having and imposing on societies everywhere.
When the secular leadership gets weak the spiritual leadership needs to step in and give them guidance, and that's what's not happening these days because the spiritual leadership is itself weak. The world’s spiritual leadership needs to recognize its own weakness and to fix its own house before it could address the larger challenges facing the social order.
