The Biden administration has approved a $20 billion arms sale to Israel as tensions rise in the Middle East.The State Department says Congress was notified of the sale, which includes more than 50 F-15 fighter jets, air-to-air missiles, tank ammunition, mortars and tactical vehicles. The jets are the biggest part of the funding package and include the promise of new aircrafts and upgrade kits for Israel to modify its existing fleets.But they aren't expected to get to Israel anytime soon. Contracts for these weapons take years and are meant to help Israel long term.Meanwhile, the Biden administration is attempting to balance its support for Israel with growing calls to curb military support due to civilian deaths in Gaza.The administration is calling on Israel and Hamas to come back to the negotiating table for a ceasefire as soon as Thursday. It will likely go unanswered.
