Writing the Independence Day review-turned-recap reminded me of a quirk of Ronald Reagan's. While president he on multiple occasions in his speeches went on to say that if humanity came under attack by an extraterrestrial specie our "local" differences would quickly evaporate.
In the midst of all the embarrassing and cringeworthy speeches Reagan ever made, the alien attack pitch was a sole example of something that, albeit overly optimistic, actually made sense. Yet it is the one thing he said he still gets ridiculed for. Figures.
Then again it is a condemnation of Reagan's like no other that the most sense he ever made was when worrying about an alien invasion.
