I think the Daily podcast today framed it pretty well from both sides’ perspective. You’re welcome to take a listen, even though it may not fit your narrative around here.
Essentially, Israel got their cojones because they saw how Iran didn’t do much to react to the assassination of Soleimani. So Israel acted on the consulate. The Biden administration was unhappy about it, but Israel is an ally (I don’t need to tell you that Iran is not), and so when Iran retaliated, UK and US came to their aid.
It's that simple, not that hard to understand, allies gonna align, and Israel is an important one in the region.
The difference, from an Israeli perspective, is that Iran didn’t use one of their proxies to retaliate this time, and that is a significant difference. The US allowed tit for tat last time and then let it slide, at least publicly. It seems that Israel’s hardliners aren’t willing to let this one “slide”, they want to continue tit for tat. I’m hoping cooler heads prevail before this dominoes.
