"Iron laws of the world"? Some of America's most important national accomplishments are about leading humanity away from this kind of bullshit.
If we let ideologues like Stephen Miller drag us back into a world where brute force is all that matters, all of us will be less safe.

In a waiting room, listening to local news. Why do they recount every crime-related death but not infectious disease-related deaths? Is that because the news would be too long?
What would the effect be? More funding for public health? Politicians talking about how they'll bring down flu?

It's great that reporting on the double tap has spotlighted the abject criminality of this Administration.
But don't forget: Venezuela is not waging war on America or Americans, and the men killed were not combatants.
The first strike was every bit as illegal as the second.

Polio virus found in the wastewater in Hamburg, Germany. This is wild type - much more likely to cause paralysis than the outbreak in New York State in 2022. (Estimated paralysis for 1 in 200 un-vaccinated infections.)

Wild-type polio detected in German sewage—this is *actual* polio, not vaccine-derived virus. This will probably be a one-off event, but it shows the real potential for polio reintroduction into under-vaccinated communities.
