Sooner or later it will work... right? ?

.... why did you think Russia are losing, exactly? Is it just a magic coincidence that the country that's been sanctioned have massive supply issues on their military logistics? Honestly, I'm really curious to understand how you think that works.

Why do you think Russia is losing? They were trying to preserve infrastructure, now they don't care. Watch and learn.

You actually have a point here in a way. It would agrovate them more and many sanctions only really seem to target civilians instead of the army. Better management of sanctions should be pursued.

And it’s worth noting that sanctions were slightly key towards deterring the Russians.
