The context of this doesn't really matter. It doesn't really make sense in any case. All you really need to know is that Nazi robots are invading Washington D.C. and that the Smithsonian Institute, The Lincoln Memorial, and the ghost of George Washington won't stand for that.
Usually its pretty obnoxious when comics try to do politics. At best, it comes across as stilted and pandering. This isn't exactly subtle, but at least it embraces the ridiculousness of injecting politics into superhero stories.
