Between this comment and the username, I think the probability tilts towards this username being trollish. That's not allowed on HN, so I've banned this account. https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...

If you'd like to pick a different username we'd be happy to change it for you. Email hn@ycombinator.com in that case.

After Germany had taken Austria, Sudetenland and Poland, isn't it.

With a username like that, you should be careful to comment on WW2.

After Germany declared war and invaded Poland. Poland was an ally of both Britain and France. No question who started WW2, and who wanted it from the get go. It was the Germans.
