The U.S. is deploying 2,000-3,000 paratroopers from the 82nd Airborne to the Middle East amid mixed signals about Iran negotiations, while Israel threatens a ground invasion of Lebanon using the "Gaza model" and Congress struggles to fund DHS as TSA workers remain unpaid. The 82nd Airborne deployment could serve as either a negotiating pressure tactic against Iran or signal imminent military action, with potential missions including seizure of Iran's oil export hub Karga Island.
