Yom Kippur War
On the Egyptian front, Israel's attacks against Syria had served as a 'distraction' against the Egyptian offense. That allowed the Egyptian army to dig around 12 km deeper into Sinai, an extra 2 km to the original plan. Israel feared a massive military defeat and so called on America for aid. Initially, The US refused and so Israel threatened to use its nuclear weapons. That was enough to persuade US President Richard Nixon to send aid to Israel. America conducted Operation Nickel Grass, which gave Israel a resupply of 22,000 tons of military equipment and ammunition, as a response to the parallel Soviet supply operation in which 15,000 tons of equipment were airlifted, and 63,000 tons of equipment were sealifted. That aid was deniend at the time but was vital to Israel and allowed it to continue fighting despite being heavily outnumbered, according to Henry Kissinger.
