Israel will have no choice other than to respond to this Iranian attack, as every country would. The IDF has of course been preparing for that as well, perhaps by striking military targets inside Iran and other countries from which any missiles or drones are launched.
As the US sought to prevent Iran from attacking Israel by intensive diplomatic efforts, the Biden administration will likely try to pressure Israel to limit its retaliation, in other words to de-escalate. However, even if limited damage is inflicted in this attack, Israel should strike back hard – perhaps with even greater strength – to deter further attacks.
While hostilities directly with Iran are unlikely to expand beyond air attacks and possibly naval conflict, a major attack by Hezbollah might well lead to an all-out war in Lebanon, which has been on the cards since October.
This latest development in the Middle East shows that this is not just a conflict between Israel and the Palestinians. The war in Gaza was initiated by Hamas and Islamic Jihad, both Iranian proxies, and has been joined since the start, in the form of attacks on Israel, by Tehran’s proxies in Lebanon, Syria, Yemen, Iraq and the West Bank.
The ayatollahs have been declaring their intention to eradicate the Jewish state for many years and have built a proxy “ring of fire” around Israel to achieve that, as well as working on a nuclear weapons programme.
However this conflict develops, Israel’s allies, including the US and UK, must do all that is needed to stand strongly by their main ally in the Middle East, if necessary with military action. Failure to do so will increase the prospects of escalating conflict in the region.
