Christopher Woody: As mentioned in the title of your book, there have been several battles for the Atlantic, namely during World War I and II and the Cold War. How does the present situation resemble those battles and how does it differ?
Woody: Russia has made an effort to rebuild its navy in recent years. What capabilities does that force, its submarines in particular, have now that it didn't have in the years after the end of the Cold War?
Woody: On the Center for a New American Security podcast in August, you mentioned that when it comes to dealing with Russia, you think there's less an "Arctic problem" and more of a "Kola Peninsula problem." Can you elaborate on the difference between the two and what that distinction means for NATO?
Woody: The Arctic remains a challenging region for navies to operate in, but climate change is altering the environment there. What changes do you expect naval forces to have to make in order to keep operating there effectively?
