You can yoink that word from my cold, dead hands!

I even looked through the article to see if it is mentioned somewhere at least but no. They give a four hour battery as an example but is that representative? Who knows 🤷

Effective at what? Germany capitulated only once it was almost fully occupied (e.g. Berlin, Rhineland). The bombs might have helped by binding resources and demoralizing the population but that didn’t affect the capitulation directly.
