The gamble has already failed. Russia has damaged its standing beyond repair for the foreseeable future. There is a lot of information missing as to it’s decision to halt, but it seems to me that Russia moving beyond SO borders, and not capturing Tbilisi means it failed. It could have stayed in SO, and not have damaged it’s standing. At this point it appears that Putin miscalculated somewhere, either the speed with which Russian military can accomplish the objective, or US response (which we still dont know).
