I am not being very consistent with the name of the comic. But neither is DC. Yes, it says "Justice League of America" on the cover, but they still have JLI listed in that little box where the barcode would go. So, DC, what's the story. I guess that would indicate that the JLA is, overall, a part of the JLI, which would also include the JLE. That's a lot of JL.
It's the "last giant nazi robot" story. Somewhere in South America, there is an underground rest-home of retired Nazi generals that just want to be left alone. But not Herr Schmidt. He still has a burning desire to destroy General Glory, and has come to get the others to agree to using a secret project -- Weapon H -- to crush him. And, somewhere in Maryland, there is another old shadowy government operative that knows something about General Glory.
Project H turns out to be a giant Nazi robot (that looks a lot like Hitler himself) that has been buried beneath Berlin. When activated, JLE is called (but they are busy). 
There are some great lines between Sue Dibney and various people regarding the giant robot.
We finally get General Glory's orgin story. I think his sidekick, Ernie, explains Guy's haircut.
Long story short, JLA fights giant robot, beats it, and then figures out that somebody bad is after the General. Oh, and he is arrested -- General Glory, I mean.
