The war of words between Donald Trump and North Korea is getting worse. People are worried there could be a real war. North Korea said it had nuclear missiles. Trump then warned that North Korea would, "be met with fire and fury like the world has never seen". North Korea now plans to fire missiles near Guam.
Mr Trump said North Korea should "be very, very nervous". North Korea said Trump's words were "nonsense". The Arms Control Association said Mr Trump's words were dangerous. It said Trump's words would not stop North Korea becoming a nuclear power. It added that a war would not help the USA.
