Ukraine has about 60,000+ troops training outside of Ukraine in NATO countries. Once the ground dries we will be able to see the impact of this freshly trained forces, hopefully with western equipment. The ground should dry in the south sooner than the northern areas of Ukraine. The most obvious move is for Ukraine to advance in the south and cut off Crimea. For this most obvious move the Russians know it to. Last year the Ukraine's indicated a advance towards Kherson and then did a head fake and launched counter attacks in the North. Ukraine is going to need to figure out a way to throw the Russians off as to what will be the main point of advance for them. Ukraine could wait until Russia strikes and then launch a counter attack. However this would force them to wait, which might not be a option for Ukraine. They are going to need to show they can successfully attack and take back large chunks of their country in the spring-summer of 2023. If this doesn't happen and we get into a stalemate, the west will be more likely to push for negotiated settlement. Russia knows this and hopes by throwing soldiers into the breach they can string things along enough for the west to loose interest. The Republicans so far are playing right into the Russian hands.
