Your concern about “the privatization of faith” is well taken. However, the response to this may not be to develop a public theology that gives us the idea that we can discern which nation is good or bad.

At the moment of a conflict between nations we do not know how God is working. His ways are beyond tracing out. Who would have figured that the New Exodus for Israel and the welcoming of the Nations would have occurred the way it did through the Jewish rejection of their Messiah. I think I am with you that God is involved on the geo-political stage (contra Sbryan) but I do not think we can know how. In other words, judging between the nations is like picking fruit from the tree of the knowledge of good and evil. And we know where that gets us.

But it seems to me that we do know how we (the church) should respond to our enemies in the time of conflict: love. This Andrew is what I think the Spirit of God is for. I would expand Sbryan’s point about “glimpses of the Kingdom” from the individual level to the corporate level of the church. We are the foretaste of the Kingdom. This is the glimpse of the Kingdom the world needs to see and experience.
