Britain ‘must stop relying on US for defence’

Britain's Armed Forces minister Al Carns warned the UK can no longer rely on US security guarantees “for the last 60 years” and urged NATO members to increase defence spending to “increase our lethality,” citing concern that a Trump White House could pivot away from Europe. His comments come as NATO Secretary‑General Mark Rutte warned Vladimir Putin has chosen the alliance as his “next target” and as President Trump has publicly attacked European leaders and issued stark migration and security rhetoric. The juxtaposition of US unpredictability and escalating threats underlines pressure for greater European strategic autonomy and higher defence budgets to bolster NATO readiness.

Analysis

Armed Forces minister Al Carns said Britain has been dependent on US security guarantees “for the last 60 years” and warned that a Trump White House could pivot away from Europe, urging NATO members to increase defence spending to “increase our lethality.” His remarks follow NATO Secretary-General Mark Rutte’s warning that Vladimir Putin has chosen the alliance as his “next target,” and come amid President Trump’s public criticism of European leaders and a US national security strategy that flagged migration and European vulnerability.

The immediate policy implication is heightened pressure for European strategic autonomy and higher defence budgets across NATO members, which would favor defence procurement and infrastructure spending. The article’s sentiment is moderately negative with a hawkish tone and a market impact score (0.6), indicating a likely re-rating of defence-related risk premia even as broader investor sentiment may become more cautious.

Key near-term risks are timing and political uncertainty: budget increases require parliamentary approvals and may be offset by competing fiscal priorities, while US policy volatility could change the calculus rapidly. Investors should therefore prepare for a scenario of greater defence spending and elevated geopolitical risk while recognizing execution and timing risk on actual budget commitments.

Key Decisions for Investors

• Consider a modest overweight to European and global defence contractors and suppliers that would benefit from sustained higher NATO/EU defence budgets, while keeping position sizes conservative given political and timing uncertainty
• Monitor concrete policy triggers — formal defence budget commitments from major NATO members, EU strategic autonomy initiatives, and US national security pronouncements — before materially increasing allocations to the sector
• Increase liquidity and consider shortening duration in Europe to prepare for potential fiscal reallocation toward defence and a widening geopolitical risk premium, and use hedges (currency or volatility) to protect portfolios against escalation
