They are going to need to find a way to bring some men back into the country if they plan on rebuilding in the future, because there won't be any Ukrainian men left to do it by the time this is all over.
"What could the government of Ukraine do to increase the population of Ukraine? The same thing that the European community is doing: attracting migrants, says Oleksandr Okhrimenko. - Simplify the system of obtaining citizenship, develop a program for the integration of foreign citizens into Ukrainian society, help develop various ethnic "communities". The economist is convinced that programs aimed at increasing the birth rate will not yield anything: "The European experience has shown that it does not work. The wealthier or more modern young people are, the fewer children they have."
