So is Russia. Russia was unable to help Armenia, what we see in Syria, there are some signs of things breaking up in Libia, Georgia, we will see how Belarusian election will go in January, last time Putin needed to send his military to stop the protests.
The war economy cannot work forever and 2024 was estimated to be its peak for Russia.
The support the West is providing also is negotiable (compared to GDP) and if Russia will win in Ukraine we will have to spend 7 times more while being in actual war according to analysts.
They are doing this on purpose to exhaust, and when we are exhausted they can get what they want.
Pick your battles, don’t stress over things in advance that you can’t control.
