I want to know the answer to the following question:
What country was Alsace annexed to?
All the background I'm provided with is that "The last Jews were deported on 15 July 1940 and the main synagogue, a huge Romanesque revival building that had been a major architectural landmark with its 54-metre-high dome since its completion in 1897, was set ablaze, then razed.". Is that enough to answer the question?
Answer: no
