"Battleship" is the smartest dumb movie in recent years

Okay I don't know if somebody has pointed this out before, but I've never seen it discussed on the odd time that Battleship is brought up.

I think that "Battleship" (2012) is actually a subtle and deliberate commentary on the human (and maybe American specifically) propensity for war and bloodshed, disguised inside an expensive action blockbuster. Okay maybe it's not that subtle, but it's never really made explicit either.

The aliens, whoever they are, are in fact the "good guys" in that they are a fundamentally peaceful race who were investigating the signal sent out by Earth. They were eager, I guess, to seek out other intelligent life. Except that with their communications ship destroyed as they entered the atmosphere, they immediately deployed a defensive perimeter (dome) since they no longer had any way to signal back home for help if things went south.

At no time do they ever deliberately attack humans. All the death and destruction results solely from the Navy persisting in being aggressive or directly attacking the now vulnerable alien ships. They attack Hawaii and its military bases, for example, solely as an attempt to disable military efforts. The movie goes to great pains to show that they will not attack human beings unless they are posing an IMMEDIATE threat.

So in the end, despite vastly better technology, the stranded aliens are slowly picked off by the hostile and bloodthirsty inhabitants of our planet. From their perspective, "Battleship" is a hopeless horror/survival thriller.

And the cherry on the cake is the decision to play "Fortunate Son", a famous anti-war protest song, over the main credits.

Anyway I know the movie is no Apocalypse Now, but I like it for being pure dumb fun. But I wondered if anyone else noticed something like the above.
