Group 1 - The core viewpoint is that nearly 30 European countries have committed to increasing defense spending to 5% of GDP by the 2025 NATO summit, with 3.5% allocated for core defense and 1.5% for broader security [1] - The overall difficulty in achieving the target for European defense spending is highlighted, with an estimated total spending increase of $5.8 trillion, of which approximately 46% is expected to be concentrated in Germany, the UK, and France [1] - In terms of investment direction, about 23% of the $2.9 trillion increase in core defense spending is anticipated to be used for equipment purchases, benefiting European and US-Korean defense contractors [1] Group 2 - Approximately 54% of the $2.9 trillion increase in broader security spending is expected to be directed towards energy and infrastructure, which may stimulate demand for imports in critical materials (such as titanium and hard alloys), energy equipment (including grid equipment, energy storage, and components for new energy equipment), and engineering machinery [1]
