Signal Trump 2.0 techno-nationalist measures pull US support from global public-good science

Summary

While the international community discusses transformative innovation for the global public good, the essay observes that real-world policy is decoupling from it. Under an 'America First' banner, the second Trump administration is shaking the global STI landscape with techno-nationalism that denies the publicness and openness underpinning international science cooperation. On directionality, the essay lists a renewed withdrawal from the Paris Agreement, a halt to Green Climate Fund contributions, cuts to 2026 budgets for EPA, NIH and NSF, reduced DOE clean-technology R&D and a spreading energy-dominance discourse. On inclusiveness, it cites limits on US scientists' participation in the IPCC, ended support for critical NGOs and politicised scientific advisory bodies. On systemic coordination, it points to AI moratorium disputes, attempts to repeal the Inflation Reduction Act, arbitrary expansion of the foreign direct product rule and a push toward bloc-based research security.
