One can simply wonder how much progress is being kept secret from the world due to nationalistic bullshit. To be honest, I'd not be surprised when in 2060, someone says "we had all the stuff in the Avengers movies as actual, real technology back then".
And one can only wonder if the hundreds of billions sunk into programs like the F35 or the European A400M program haven't simply been used to fund skunk works projects instead.
