for the Russian people is a tribute to the tradition, for the army it is good training and for the military industry exhibition of new products
Russian people should stop living in the past, desperately trying to live out the glory days, that well, were hardly actually glorious and long time ago.
Spending time actually training would have been better training.
The fact that beound oil, gas and military your country has absolutely no other means of reasonable profit or nothing else to show at all, is just sad. If your people are truly desperately in need of "tradition" via military parades, than my friend, you are hardly in the modern times. You wanna know how normal people in normal countries react to military showoffs? With a simple "meh".
Like I said, weak, fragile countries.
