As you may have heard, Russia is invading Egypt. This is not because there are masses of Russian-speaking Egyptians who want to be integrated back into Mother Russia, as Putin claims is the case in the Ukraine. No, it is simply because when visiting Cairo, Putin had to endure this astounding rendition of the Russian national anthem:
This is the first ever casus belli that can be attributed to orchestral mangling, intentional or not.
Of course, Russia has the symphonic resources to reduce the Egyptian national anthem, whatever the heck that may be at this time, to chicken cackling and cat yowling.
But Putin being Putin, naturally he prefers tanks.
