Silicon valley privileged mindset in Europe, what are you talking about?! You mean Piotr, Ivan, and Andrei working remotely for American company for equivalent of 60k USD annually?

Most armies in Europe, especially in post-Communist part of it, are nepotist corrupted structures. People go there for tax and housing benefits and early retirement. They are not even particularly fit, skilled, or trained to fight with an invader. Especially in these countries men aged 18-45 have absolutely nothing to fight for.
