Trump has triggered fears that Europe’s nuclear deterrent is weak. Can Britain and France confront Russia without the United States?

Donald Trump’s suggestion that the United States should abandon any NATO* ally that fails to meet the alliance’s defense spending targets has shaken Germany. A German minister has called on Britain and France to deploy a “nuclear shield” over Europe to deter a possible Russian attack. There are calls for a nuclear shield amid concerns that NATO may no longer be able to rely on U.S. support if Trump returns to the White House. Germany’s finance minister says it’s time to consider working with nuclear powers, France and Britain to build a European bomb.
