On 10 February Boris Johnson met the head of the NATO defence alliance in Brussels and then travelled to Poland in support of NATO allies. He warned that the Ukraine-Russia crisis is at its ‘most dangerous moment’ and that war would be an ‘absolute disaster’. Russia is still massing troops on its neighbour's borders and in Belarus. In Moscow Liz Truss, the Foreign Secretary, said that continued ‘aggression’ will lead to ‘severe consequences’, but at the same news conference her Russian counterpart Sergei Lavrov accused the West of ‘hysteria’. Moscow wants the West to rule out Ukraine ever joining NATO - but Boris Johnson said that every European democracy must retain that right. Johnson warned that the possibility of an invasion ‘remains grim.’
