The west has already spent out of seven billion helping ukranes public finances. The finance minister said recently that ukraine urgently needs more money. There is little appetite in markets to lend money to a country at war, so the funding will have to come from the west. If you had all that on top the loss of intrstructure, physical intstructure of around 120 billion us. Dollars is what the prime minister of ukrane recently estimated. May not be far off.
