Common sense would tell you that if Hamas, Hezbollah and Yemen are the proxies for Israel that Iran really is all in for this war with Israel. However, their hand was forced because they thought Israel would sacrifice the Red Heifer, that is what prompted this October 7 attack.
However, common sense would also tell you that Israel has provoked this war with Iran, most likely because they are concerned that Iran is about to get a nuclear bomb. So although Iran wants war with Israel they aren't ready just yet. So both the October 7 and the April 1 attacks were forced onto Iran before they were ready.
So Israel knows they will have a war with Iran and they want the war before Iran gets a nuclear bomb. However, Israel is concerned about the UN and public perception, so they are trying very hard to not appear to be the aggressor.
If we assume this is the mindset of the two now let's look at the events. Israel does this attack on the Embassy compound. You can argue about whether or not you can have a consulate on the same land as an embassy, or whether it should simply be viewed as a military base. The point is they knew it would provoke a response from Iran and sure enough it came from Iran itself and not their proxy. However, Iran stalled for 12 days. Israel also claims they will wait till after Passover, and yet attacks before. Iran's attack looks huge in many ways but in reality was small and surgical. Israel's seems quiet and minor but in reality is probably very significant hitting key strategic secret military targets.
Iran had threatened to retaliate in seconds but now is giving a very different response. Everyone is doing the opposite of what they say.
So then let's consider the objective. In Iran's attack it seems the objective was two fold. First let Israel know that they cannot shoot down Iran's best missiles and second, to tell Israel that we can counter your million dollar missiles of the Iron dome with thousand dollar bombs from drones. You can shoot down 293 of our missiles but it will cost you $billions and when you are done you will be out of missiles.
Israel is saying "our intelligence is top notch, we know where your generals are, we know where your secret bases are, and we know how to exploit the weakness of your air defense". They are also saying the next strike will be against your nuclear weapons.
So if Iran is a month away from a nuclear bomb and they decide "let's wait a month" they will appear weak. That doesn't work. So instead the other option is to try and take out the ability of Israel to strike their nuclear reactors. But, a strong response will provoke an even stronger retaliation from Israel. They can't wimp out because they could lose Hezbollah, Hamas and Yemen. You could try and coordinate a big attack with all the proxies at once, but since Israel's intelligence is so good they would get a heads up. So then, just like Jesus crucifixion when the leaders said "not at the feast lest there be an uproar" I suspect Iran will be forced to attack when they least want to. Besides there are rumors leaked that the heifer will be sacrificed at Passover. Since October 7 was done to prevent that sacrifice it is reasonable that Iran will be forced to do something this weekend.
