We are inviting blood bath with our pin-pricks.
There are loyalty issues in the Ukrainian military, that are sure to complicate issues should they come to blows with Russia. Many units will defect to Russia, and many will not have the stomach to fight (Especially those from the East).
This is not about troops and materiel ratio. Russia’ economy will crumble under the weight of war, occupation and having to feed the occupied territories population. For Russia it will be a war of aggression, for Ukraine -the war of liberation. Not everybody in Russia has the stomack for it. Us does not have to get involved militarily.
The tank number is interesting to me. Ukraine is very “heavy” on paper.
Of course, most of the Ukraine troops in the area will not fight.
This is a civil war. We would be wise to stay out of it.
Your still thinking obsolete, this is the age of 4th generation warfare. Its why Russia lost in Afghanistan.
The key is the people - if they are willing to fight it will be too costly for Russia like it was in Afghanistan despite their military superiority.
