Is committing 3% of GDP to defence spending the right priority over other public services?

The UK currently spends around 2.3% of GDP on defence, with a commitment to reach 2.5% by 2027 and pressure to increase further amid rising threats from Russia and global instability. NATO allies have set a 2% target, but several countries including the UK are debating higher levels to meet security needs. Higher defence spending would require reallocating funds from areas like health, education, and welfare.
