“Published during the time of U.S. participation in the Korean War, Junior Books’ Atomic War! Speculated on the possibilities of World War III. Despite the series’ stated purpose to warn against the horrors of atomic warfare, it did just the opposite. In its stories, U.S. forces employing tactical and strategic nuclear weapons triumphed repeatedly over the Communists.”
According to Scott Shaw at Oddball Comics: “This is one of many comics that reflected our national paranoia during the Cold War of the 1950s and early 1960s. The cover depicts the atomic destruction of Manhattan (note the crumbling Empire State and Chrysler Buildings.) Here's a quote from the issue's first story, "Sneak Attack."
"Look upon the pictures of our giant cities hundred of years in the building, smashed by the atom-bomb, and say: this shall not come to pass! More than ever today, only a strong America can prevent this from becoming a reality!"
Ace Comics was a publisher of comic books during the 1940's through mid-1950's. Like many comic book publishers of the day, the earlier series included costumed superheroes. As trends in the comic book market changed, the focus shifted more to other genres, such as crime horror and romance. The company ceased publishing comic books in 1956.
