Russia is probably gonna experience a huge shift after this, and most likely in a negative way.
The first ones that were sent ended up with food that expired in 2015 (there was a video of it) and that is not really the type of situation you would be in if you cared about the war. They fired some missiles, they killed some people, they took the lands they wanted to take and now they are going to just relax and keep the situation as it is. The thing they will want would be asking the new two lands and crime to be accepted and they will leave.
Everyday they are not given that, there is a whole miles long army marching everyday, one day they will eventually arrive and that is when things will go ugly. I am hoping that I am wrong, otherwise it will be nasty war all over again, and what we have seen so far would be like a street fight compared to what's coming.
