The real question is, why would the British public fight for the current government..?

“…We identified two key lessons. First, our deterrence strategy towards Russia clearly failed. If we are to restore the credibility of NATO’s nuclear and conventional deterrence posture towards Putin, we must develop a clearer understanding of the reasons for this failure.”

“Secondly, the invasion exposed significant weaknesses in both the UK’s and NATO’s military strength, and the UK’s ability to sustain large-scale warfare. Successive governments have attempted to maintain the notion of the UK as a global power, but the war in Ukraine has been a wake-up call, laying bare the gap between that ambition and reality.”
