If Diversity Is Our Strength, then Austria-Hungary would have won WWI.
Britian and France had more diverse armies. They recruited Asian and African troops from their colonies.
Extraneous political agendas are a military death wish. So are pre-conceived notions.
If diversity were a weakness, General Brusilov’s superior tactics would have floundered.
Russia is diverse. Ukraine is diverse. Israel is also diverse.
Diversity must be managed and sometimes used. But it remains an extraneous political agenda. And only pragmatic focus is an intrinsic strength.
