Should the UK prioritise defence spending despite strong pre-war growth?

UK defence spending stands at 2.3-2.4% of GDP, with plans to rise to 2.5% soon and potentially 3% by 2029 or 3.5% by 2035. Military leaders and former officials warn this remains insufficient amid rising threats from Russia, China, and others in a 'pre-war' era. Government faces pressure to accelerate amid competing demands like welfare and debt interest exceeding £100bn annually.
