In a Monday meeting with U.S. Chairman of the Joint Chiefs of Staff Gen. Charles Q. Brown Israel’s Defense Minister Yoav Gallant warned “Iran’s aggression has reached an all-time high” as the U.S. scrambles to broker a cease-fire deal with Hamas after nearly 11 months of war.

“To counter this, we must work together to achieve and project groundbreaking capabilities in all arenas,” Gallant said according to a readout of the meeting from Tel Aviv, which was also attended by Israel Defense Forces (IDF) Chief of Staff Lt. Gen. Herzi Halevi.
