The US has already begun delivering critically needed munitions and military equipment to Israel, and the Pentagon is reviewing inventories to see what else can be sent quickly to boost its ally, a senior Defence Department official said.
Planes have already taken off, said the official, who declined to provide details on the weapons.
The official, who briefed reporters on condition of anonymity to discuss sensitive shipments, also warned that the US is closely watching Hezbollah and other Iranian-backed groups, noting that the decision to shift American ships in the region was to deter any of them from entering or expanding the conflict against Israel.
The weapons movement came as President Joe Biden announced that the US death toll in the war has gone up to 11.
“Flooding the zone”
The official said the US is “flooding the zone” with calls and other messages so that extremist groups and other nations know they should not question America’s commitment to supporting the defence of Israel in the wake of attacks by Hamas.
The official, however, would not comment on whether US military forces would be used at all.
While the official said the US has the ability to support weapons needs in Ukraine and Israel and maintain security for America, the rapid delivery of munitions to the new war has raised concerns.
Congress must pass more funding quickly for the US to be able to give both Israel and Ukraine the weapons and munitions they both now need, army secretary Christine Wormuth said on Monday.
“The intent is to lean forward in support of Israel,” she said. “But in particular with munitions and the ability to support Israel and Ukraine simultaneously, additional funding is needed to increase our capacity to expand production and then also pay for the munitions themselves.”
It is clear the administration is now facing potentially competing requests from Israel and Ukraine for additional weaponry.
And while there is strong bipartisan support in Congress for aid to Israel, the next steps are uncertain, with the House lacking a leader after the ouster of the Republican speaker and the Senate out of town until next week.
Also uncertain is whether the debate over further assistance to Ukraine, which is opposed by a group of hard-right Republicans, will complicate efforts to pass assistance for Israel.
Ms Wormuth, speaking at the annual Association of the United States Army conference in Washington, said the administration is still “in the early stage of the process of evaluating our ability to support what the IDF needs,” referring to the Israel Defence Forces.
What weapons will the US provide?
She did not provide details, but Doug Bush, the army’s assistant secretary for acquisition, told reporters at the conference that conversations are under way about what the US can provide. He said it likely will be a wide range of equipment, from small arms to sophisticated munitions.
Most of the weaponry sent already to help Ukraine has come from army stocks and defenec contractors at a rate that has challenged the global supply chain, and while the army has recently ramped up production of some critical lines, such as 155mm ammunition for howitzers, they are not yet at full speed.
With a new ground offensive in Gaza imminent following the Saturday surprise attack by Hamas, army officials said Monday they were concerned about the ability to meet additional demand for ground munitions and that Congress needed to act quickly to provide help in time.
In addition to the 11 American citizens whose deaths Mr Biden confirmed, an undetermined number of remain unaccounted for. It was not yet clear if the missing are dead, in hiding, or had been taken hostage.
Biden said the US believes it is likely that American citizens may be among those being held hostage by Hamas, but officials are working to confirm that.
“I have directed my team to work with their Israeli counterparts on every aspect of the hostage crisis, including sharing intelligence and deploying experts from across the United States government to consult with and advise Israeli counterparts on hostage recovery efforts,” Mr Biden said in a statement.
Hamas attack
The attack by Hamas and Israel’s response have left more than 1,100 dead and thousands wounded on both sides.
In the aftermath of the Hamas attack, the White House has asked Senate leaders to fast track confirmation of President Joe Biden’s nominee to be the next ambassador to Israel, former Obama-era Treasury Secretary and White House chief of staff Jack Lew, according to a US official who was not authorised to comment publicly and requested anonymity.
The White House has received assurances that the Senate Foreign Relations Committee will push forward hearings for Mr Lew, the official added.
The US is currently without an ambassador after the departure of Ambassador Tom Nides in July. Mr Biden nominated Mr Lew in September.
Defence secretary Lloyd Austin said on Sunday he has ordered the Ford carrier strike group to sail to the Eastern Mediterranean to be ready to assist Israel.
The USS Gerald R Ford, the US navy’s newest and most advanced aircraft carrier, and its approximately 5,000 sailors and deck of warplanes will be accompanied by cruisers and destroyers in a show of force that is meant to be ready to respond to anything, from possibly interdicting additional weapons from reaching Hamas and conducting surveillance.
The senior Defence Department official said worries about Hezbollah opening a second front of violence against Israel was the main reason for moving the ships to the Eastern Mediterranean.
Hezbollah
The official said the US is deeply concerned Hezbollah and other Iranian-backed groups will make the wrong decision to try to “pile on” and widen the war.
Along with the Ford, the US is sending the cruiser USS Normandy and destroyers USS Thomas Hudner, USS Ramage, USS Carney, and USS Roosevelt, and the US is augmenting Air Force F-35, F-15, F-16, and A-10 fighter aircraft squadrons in the region.
The Norfolk, Virginia-based carrier strike group already was in the Mediterranean. Last week it was conducting naval exercises with Italy in the Ionian Sea. The carrier is in its first full deployment.
Senior officials from the Pentagon and State Department briefed senators on Sunday night, and majority leader Chuck Schumer said they were assured that the US was giving Israel “everything they need”.
