The crisis in Ukraine is creating a massive refugee problem, but the answer is that NATO and the United States MUST welcome Ukranian refugees, whether Ukranians or other nationalities, who are escaping the war against Russia, with welcome arms!
Nativism is totally unacceptable, so all of the nations in NATO, including the US, must welcome however many refugees are required, and overcome the hatred and bigotry promoted by Donald Trump and right wing talk radio and cable news stations, including Fox News Channel, One American News Network, and Newsmax!
America has always been a land of immigrants, including people escaping oppression, so there cannot be any attempt to close the doors, but rather accept the responsibility of a decent government and people to admit refugees and help them to recover from the wounds of war in their homeland!
