An extraordinary NATO summit has addressed the most serious security crisis in a generation. NATO's core task was to address the need for a reset of deterrence and the defence of Ukraine in the longer term. Four new battlegroups have been established in the eastern part of the Alliance. There is a new sense of urgency as many countries invest more money in Ukraine and supply essential air, sea and land equipment to defend it and deter attack. President Zelensky, addressing the leaders, asked people everywhere to take to the streets in a show of support for Ukraine to mark one month of the Russian invasion. The UK sanctioned 65 more Russian individuals including the Wagner Group of mercenaries, described as ‘Putin’s private army’. When the NATO meeting ended leaders left for a G7 meeting where sanctions were discussed. See also
