Key Takeaways 1) IAWN just opened a formal “comet campaign” on 3I/ATLAS, elevating astrometric tracking to stress-test the world’s warning network. 2) DART proved kinetic deflection is real, giving policymakers a non-nuclear playbook while nuclear posturing resurges. 3) Trump’s order to restart U.S. nuclear testing reframes space-hazard preparedness inside a broader full-spectrum deterrence environment, even The International Asteroid Warning Network (IAWN) targets 3I/ATLAS in a precision tracking drill as Trump orders immediate U.S. nuclear tests, aligning civil planetary defense with renewed deterrence politics.
