<h1>US foreign policy: Secretary defends military actions against Venezuela, says operations don't require congressional approval.</h1> The Secretary said negotiated settlements in Ukraine and Gaza require reciprocal concessions and U.S. efforts aim to 'nudge' both sides toward agreement, while the administration's military actions against suspected narco-trafficking in Venezuela are described as directed at 'narco-terrorists' and supported by 'very strong legal opinions' that neither require congressional notification nor cross the threshold into war.
