“Iran fired missiles toward Gulf Arab states… explosions were reported in multiple cities."

“Kuwait said it intercepted drones… part of the Iranian retaliation.”

“Israel struck Hezbollah targets in Lebanon following cross-border attacks.”

“U.S. and Israel launched large-scale strikes on Iran…”

This stopped being U.S. vs Iran the moment retaliation crossed borders.

Definition (so we’re not talking past each other): 10+ countries = struck, intercepting, or hosting.

Question:
If the footprint is already multi-country, what’s the objective, and what’s the off-ramp?
