There is a new book out called Shattered Sword that puts forth a good argument that Operation AL was not a diversion for the attack on Midway.
The reason for this was that they were at that time the closest US assets to mainland Japan

Kiska Island was retaken with 35.000 US and Canadian troops with somewhere around 15 soldiers being killed
