This does not seem like a fair criticism or framing of the situation. Every country Germany occupied was used to support Germany's war efforts. The country had little choice but to surrender, they were hung out to dry by their allies.

Despite this, they still resisted at great personal cost. Heydrich was assassinated in Prague by Czech resistance fighters. The reprisals were brutal, with thousands killed in response. My grandmother who is still alive lived through this time. Every day at school they announced the names of those executed by the Natzis in order to intimidate the populace.
