I have thought about this off and on. Making beer requires a farmer. It requires a facility which, at any economic scale, has always required a certain level of capital investment. It requires time. Time for the grain to grow and time for the yeast to do it's work. It requires safe transportation routes. It takes people safe enough to relax and even share an hour with people not exactly like themselves. Southern Sudan is maybe returning to peace because there is now a brewery there:

More than two million people died and about four million were forced from their homes after rebels from the largely Christian or animist south rose up against the Arab-dominated and Muslim government in the north. Now, four years after a US-brokered peace deal, a giant 37 million dollar (27 million euro) brewery is ready to begin operations, with a daily packing capacity of 150,000 bottles. "We have developed a dry, crisp, thirst-quenching beer -- especially to match the climate here," said Ian Alsworth-Elvey, managing director of Southern Sudan Beverages, a subsidiary of global brewing giant SAB Miller.

This brewery clearly also speaks to greater geo-political tensions, too, as the powers of teetotalism come in many forms and are not necessarily divided by simply allocating points of view by politics, faith group or national identity. But when those things become associated with suffixes like "-ism" or "-istic" perhaps rather than "-ic" or "-al" watch how the breweries are affected and be concerned for the state of peace.
