No-fly zones are used to protect populations but implementing one over Ukraine risks sparking a wider, more dangerous conflict
Ukrainian president Volodymyr Zelenskiy again urged Nato on Monday to impose a no-fly zone over his country, saying it would protect not only Ukraine but the countries of the Atlantic alliance from Russian air attacks.
But the United States and Nato allies refused for the same reasons they have been citing since Moscow invaded Ukraine on 24 February: that any attempt to establish a no-fly zone would place them in direct conflict with nuclear-armed Russia and spark a wider, more dangerous conflict.
