Restoring Wilhelm III to the German throne in 1928

What if Germany restored the monarchy under Wilhelm III in 1928?

The restoration could provoke civil conflict and a Versailles crisis, but army support and foreign acceptance might preserve it as a barrier to revolutionary extremes.

The question begins with a restored German monarchy in 1928 and is later clarified to mean Wilhelm III, not Wilhelm II. Some participants expect French intervention or civil war. Clarke instead argues that monarchist army officers could actively defend a restored monarchy even if they had been unwilling to support the republic against street movements. A restored Kaiser might also attract support as a barrier to communism or the far right, though opponents could rally against him. The effect on Hitler's later access to office is left uncertain, with Hindenburg's possible role changing under the scenario.
