It’s the same thing in the US. I see C-130’s flying in formation and think they’re probably training or clocking flight time. OP is using terms like “militarism holidays” which I’ve never heard anyone use in conversation here, ever. We have “air shows” on patriotic national holidays like Independence day, or Memorial day. At some large sporting events like the NFL Superbowl, or maybe the MLB World Series get “flyovers” over the stadium.
The new-ish Federal Trade Commission head has been making a push to work on quite a few projects for the past couple of years. They have a very small resources and man-power compared to the war chests of multibillion dollar companies, but recently, somehow managed to bring charges against Google as a monopoly. This in my opinion is a good thing. I consider myself a social liberal and a fiscal conservative. I don’t like how our government seems to take the money of these companies and turn a blind eye as they do what they want in pursuit of the almighty dollar. I support her endeavors working for the interests of the majority of people and not those few with the most money.
