Attu - What a defining week!

Last night I viewed a new documentary which detailed the military operations dealing with Attu.
Attu is one of the Aleutian islands off Alaska. And on, I believe, June 7, 1942, the Japanese occupied this island, as well as the island of Kiska nearby.
I thought about the date in 1942 and pondered the supreme irony which occupies that period.
In occupying Attu, this operation turned out to be the nearest Japan ever got to mainland America, and during this very period Japan's ability to continue the offensive war against America was destroyed at the Battle of Midway just hours before - a truly defining week.
