Wars are dynamic you look at countries...adaptability is key all their assumptions have failed(sanctions effects etc) and Ukraine as stepped in it...before the country is dissolved and becomes a Russian territory..they better start negotiating...as only a NATO direct intervention will change their downward trend-line, which will lead to world war...and all bets are off who win’s if there is such a thing.
WAR IS A GRIM TEACHER but Russia has learned and improved with each set back. Each week they become more professional and better. Now they are on defense and Ukraine will have a fight on their hands. Napoleon taught them about massed artillery and this has helped them a great deal. If the offensive fails or stalls —Russia will win. Only a NATO intervention will stave off defeat.
