US defense chief warned by Israel about Iran's aggression reaching an all-time high.

In a Monday meeting with U.S. Chairman of the Joint Chiefs of Staff Gen. Charles Q. Brown, Israel's Defense Minister Yoav Gallant stated that Iran's aggression has reached an unprecedented level as the U.S. works to negotiate a cease-fire with Hamas following nearly 11 months of conflict.

In order to combat this, we must collaborate to develop exceptional abilities in all domains, as stated by Gallant during a meeting in Tel Aviv, which was also attended by IDF Chief of Staff Lt. Gen. Herzi Halevi.

Israel is facing threats from Hamas in the south and Hezbollah in the north, both of which are heavily supported by Iran, as highlighted by Gallant.

Although the U.S. has tried to negotiate a cease-fire with Egypt and Qatar, Hamas continues to refuse any terms as long as Israeli troops remain in security zones in Gaza.

The cease-fire talks are unclear, but on Monday Gallant reminded Brown of Israel's primary objectives in its war in Gaza, including dismantling Hamas, returning hostages, and improving security along Israel's northern border to allow communities to safely return home.

The Hamas-controlled Health Ministry in Gaza reports that 40,000 Palestinians have been killed since Oct. 7, without distinguishing between civilians and terrorists. Additionally, nearly 700 Israeli soldiers and approximately 1,200 Israeli civilians have been killed since the Hamas attack.

While there is ongoing conflict in Gaza, some security officials contend that the greatest danger to Jerusalem comes from the north, where it frequently engages in missile and drone exchanges with Hezbollah.

One day after the world watched with concern that an all-out-war between Israel and Hezbollah, and by extension Iran, had finally begun following threats from Tehran last month, a meeting took place between Brown and Gallant.

On Sunday, Hezbollah announced that it had launched hundreds of rockets and drones at northern Israeli military positions. In response, Jerusalem claimed it had fired upon southern Lebanon using 100 warplanes to launch preemptive strikes on Hezbollah strongholds. The IDF stated that no Israeli military installations were hit during the attack.

The assault in Lebanon resulted in four fatalities, including one Israeli soldier, though by mid-morning Sunday it had ended.

The reports on Monday suggested that the long-awaited attack by Iran and Hezbollah, which resulted in a relatively limited number of casualties, may have eased concerns of a broader war in the Middle East.

The threat posed by Iran remains unchanged, as stated by Major General Mohammad Bagheri on Monday.

"Yesterday, we observed only a portion of the revenge," he stated, as reported by Al Mayadeen English. "Revenge against the Israeli entity is unavoidable."

According to John Kirby, the ceasefire talks with Hamas have not been affected by the exchange of fire on Sunday.

"Despite the rocket and drone attack by Hezbollah over the weekend, which Israel successfully defended against, the progress towards a ceasefire deal continues. Our team on the ground reports that the talks are still constructive."

Kirby stated that a "sense of urgency" persists in the effort to obtain a ceasefire.
