I was calling russian army a paper tiger for a long time, citing immense corruption and deterioration of all public institutions in Russia under Putin. Military isn't public, but that's just more opportunities for corruption and theft.
My opponents usually disagreed, pointing to a big military budget and some modern-ish new weapons shown here and there. No, they do look cool at a show or a parade, but does the personnel know how to use it? Are they built en masse? Is the quality good enough? (With all that corruption!)
Turns out, things are even worse then I imagined, but in the hindsight it shouldn't be surprising: this is far from the first time in history when decaying russian institutions and imperial hubris had led Russia to a disastrous war, which was planned as a 'small victorious' one: Crimean War (1853), Japan war (1905), Winter war with Finland (1940), Afghanistan war (1980), Chechena war (1994).
Now Putin has one of his own. I hope his regime will crumble in the fallout from a resounding defeat.
