ukraine to launch a surprise. no one really expected the kharkiv offensive. sadly the russians didn t, and it was hugely successful. there s been a lot of signalling about the zaporizhzhia offensive, it may well happen, there may be room for an offensive elsewhere. carolyn, you work for the institute for the study of war which has become a byword for incredibly accurate and detailed maps, over the last year the map hasn t changed that much from a distance, the russian advances have been very small and incremental so not really since khersonm, since the russian abandoned kherson have we seen much change. do you expect in the coming months and this year, the rest of this year the battle lines to change? i would say that we are entering the prime time for ukraine to regain the initiative and really take advantage of russian weaknesses.
