He highlighted that Russia is "definitely raising the stakes and risks crossing a line" through various hostile actions, including cyber attacks, assassination attempts, attempts to smuggle technology, and reckless sabotage. Sir Richard stressed the critical need for the UK to prepare for potentially "much greater, longer conflicts," a shift from previous strategies focused on shorter, more confined engagements, drawing parallels with the ongoing situation in Ukraine. This warning precedes the long-awaited publication of the Defence Investment Plan (DIP), which has faced repeated delays and will detail future defence spending, amidst increasing calls for the UK to boost its defence expenditure. Concerns about the state of the UK's military readiness were reinforced by Lord Stirrup, a former head of the armed forces, who asserted that the UK is "badly exposed" and requires a decade to rebuild its defence capabilities.
