Today:
Welcome to this week's instalment of /r/AskHistorians' Sunday Digest (formerly the Day of Reflection). Nobody can read all the questions and answers that are posted here, so in this thread we invite you to share anything you'd like to highlight from the last week - an interesting discussion, an informative answer, an insightful question that was overlooked, or anything else.
Rundown:
/u/papiruscursor on "How could the Romans constantly raise enormous armies (in particular during the punic wars) despite not being that large of a country?"
/u/kieslowskifan answered "How accurate of a depiction is the 2001 film Conspiracy of the Wannsee Conference?" and on "Why did Germany change their flag after WW2?"
/u/i_am_oneiros on "What was Indian food like before contact with the New World?"
