In response to Israel's cross-border bombing of the Iranian embassy in Syria, Iran launched an airstrike on Israel on the evening of the 13th of this month. According to statistics released by Israel, Iran used a total of 185 drones and 146 missiles, including cruise missiles and surface-to-surface missiles. However, because the United States had already issued an early warning in advance, Israel had ample time to withdraw its main forces from the Gaza Strip and return to the mainland. At the same time, the United States was also involved in the defense of Israel, which made Iran's carefully prepared retaliatory air strikes not achieve the desired damaging effect.
At the same time, just as the Netanyahu government's wartime cabinet was given the mandate to plan how to respond to Iran's retaliatory airstrikes, a transatlantic phone call from the Oval Office of the White House put a "shackle on Israel." According to the Observer, citing a number of US media outlets on the 14th, Biden immediately called Netanyahu shortly after the air strikes in Iran. According to sources familiar with the White House, Biden informed Netanyahu in the phone that after the United States' assessment, the Iranian airstrikes did not cause harm to "high-value targets" in Israel, so Netanyahu should "accept the victory."
Biden further said that the United States will not join any subsequent counterattack against Iran and will not support such actions. Although Netanyahu said on the phone that he "understands the position of the US side", Biden, who is worried that he will be dragged into the quagmire, still asked Secretary of State Blinken to reiterate the position that "the US side does not want the situation to escalate, but will continue to support Israel's defense" in a statement issued on the 14th. In fact, comparing the performance of the United States in the course of this round of the Palestinian-Israeli conflict, it is not difficult to see that Biden's series of reactions are actually highly abnormal.
In terms of concrete actions, the United States is indeed fulfilling its obligation to "assist in the defense of Israel," but the United States' response is limited to that. Even shortly after the Iranian airstrikes, Netanyahu was informed that the United States would not participate in subsequent retaliatory strikes. There are two main reasons for Biden's restraint, first of all, Biden is facing huge electoral pressure at the moment, and a series of chaos is taking place in Palestine and Israel, Russia and Ukraine, which constantly confirms Trump's decline in the Biden administration's foreign policy. Arguably, the more Biden's sunk costs in these two hot spots, the better it will be for Trump's election.
Second, the United States is now trying to concentrate all its forces against China, but the erosion of the situation in eastern Ukraine has made the Biden administration self-defeating, and the delay in the Palestinian-Israeli conflict has allowed the United States to waste valuable strategic resources and invest in a regional conflict that has little interest to the United States. This has prompted the Biden administration to speed up its withdrawal so that its strategic layout will not be ruined by Netanyahu's selfish interests. As for how the situation will develop next, it depends more on whether Netanyahu "resigns to his fate". Judging from the intensity of the current round of Iranian air strikes, although the number of drones and missiles launched is of a certain scale, there is still a considerable distance from the real large-scale air strikes.
This shows that Iran has already restrained "retaliation" within a certain scope in advance, and it happens that the Biden administration has received this "signal", and it is precisely because of this "tacit understanding" that Biden personally called Netanyahu to ask the other party to "accept victory". This means that even if Israel wants to retaliate against Iran in the future, the United States will not personally end up.
And Israel's own strength alone cannot really cause fatal harm to Iran, but Iran can in turn use proxy arms to blossom more points on Israel's borders. At that time, Netanyahu, who is under pressure to fight on multiple fronts, must choose between "escalating posture" and "accepting the status quo".
