The level of destruction happening in Ukraine now is, while still terrible, an order of magnitude less severe than what happened in large parts of Europe during WW2. Many countries had around 10% of the population killed, and for those involved in the fighting, a large fraction where men in their most productive age.
Still, most countries had rebuilt their economy to pre-war levels before 1955, and in many cases around 1950.
Given the very small size of Ukraine's economy, reaching their pre-war level will not take very much. Should they, as I predict, come out of the war as a united nation, able to get rid of most of the corruption, they may be able to massively outperform their pre-war gdp fairly quickly.
If they return to pre-war levels of corruption, no amount of economic aid will bring their economy to western levels.
