Heck no.
Can anybody point to a "study" that we concluded during a war??
So far...nothing new. Iraq stands up, we stand down.
There were 9 investigations of the Pearl Harbor fiasco. All but the Joint Congressional Committee Investigation were conducted during the war. (the link contains links to each of them, including their report) However most of the findings were not released to the public until after the war.
The Knox Investigation Dec. 9-14, 1941.
The Roberts Commission Dec. 18-January-23, 1941
The Hart Investigation Feb. 12-June 15, 1944
The Army Pearl Harbor Board Jul. 20-Oct. 20, 1944
The Navy Court of Inquiry Jul. 24-Oct. 19, 1944.
The Clarke Investigation Aug. 4-Sep 20, 1944
The Clausen Investigation Jan. 24-Sep. 12, 1945
The Hewitt Inquiry May 14-July 11, 1945
The Joint Congressional Committee Nov. 15, 1945-May 23, 1946
I don't recall a "study group" being convened while Clinton was bombing Belgrade in favor of Albanian Muslims who were invading Yugoslavia.

Depends, would you consider the Manhatten Project a "study"?
