Rebuilding in Ukraine is focused on destroyed bridges and infrastructure as Russia continues to destroy apartment blocks, and targets the electricity grid. Many of the apartment blocks destroyed outside Kviv in Irpin in this story are hard to rebuild because of the constant attacks most recently with hypersonic missiles that are hard to detect. A couple fled from Donetsk, settled in Irpin in a new apartment only to have to flee again after a Russian missile attack left their apartment building in ruins. How do you build in the midst of a war is the question Ukrainians ask themselves every day. About 150,000 apartment buildings and half the electricity grid is destroyed, so also 1500 schools and 20,000 kilometres of roads. It would cost $350 billion to repair. It would require policy decisions on what quality of building materials and how many to apartment buildings to build and how quickly.
