Huh. The Skrulls thing hadn't pinged me at all that way, which is odd, usually I bang on and on about things like that. I think here my sense from many, many comics of the Skrulls vs. Kree as Cold War metaphor overrode the other potential coded meanings. Most of my complaining about the handling of the Skrulls in the movie was how their vision of the Skrulls didn't work within the Cold War metaphor, so I didn't get as far as thinking about what they'd replaced it with. But yes, not the best choice.
