In addition to just the difficulty posed by the breadth of what you're asking for, if there are also institutional or structural pressures which preclude such a work from existing? On the academic side, I get the sense that there is so much pressure to specialize and deeply study narrow areas that a really broad work (global developments over decades) would not be well received. Within think tanks, a broad survey would likely still need to be concordant with an institutional agenda. And if really broad documents are being produced within state departments/foreign ministries or other parts of government, we would never see them?
