In the week following Russia’s indefensible invasion of Ukraine, more than 1 million people have fled the country. The lines of refugees at the Ukraine-Poland border stretch for miles. Children cry in the freezing cold as wait times reach 60 hours. Refugees discuss the relatives they had been forced to leave behind — sometimes without knowing whether their loved ones are alive or dead. And the United Nations predicts these refugees could be followed by millions more — potentially resulting in “the biggest refugee crisis this century.”
