Europe fears the return of Donald Trump and prepares to defend itself against Russia without its help. Will it use nuclear weapons?.

If the Republican leader returns to the White House, he could distance himself from NATO in the face of a possible attack from Moscow. France is the only country in the bloc with nuclear defense capabilities. Can France play the role of insurance of last resort for Europe that the United States has played since World War II? The final decision lies with the President of the Republic, right now the liberal Emmanuel Macron.
