Hazb when fighting like conventional military vs Israel got pounded. Now they resort to asymmetrical warfare and are proving successful because this is their forte. No way they can go up against IDF in conventual warfare.
Similarly IDF is not designed for long range ground combat vs Iran. Ground ops misdirection for complex and protracted aerial campaign.
The problem for IDF and America is that they are actually fighting 2 different wars, but with the same country, Iran.
Talked to a friend of mine who now works in the Pentagon about this war. The issue here is the Israeli, and we have 2 different sets of strategic goals. The Israelis want a war in Iran because they want the Iranians to stay out of the ground operation near Gaza, Lebanon, and the West Bank, and for them to annex more land. Their entire strategy in Iran is basically just to keep them at arm's length, which can be achieved by air power only, by destroying the Iranian support network, infrastructure, and C&C.
For us, this war is about taking out Iranian nuclear capability, taking out Iranian missile capability, and taking out the regime as a secondary bonus, but we can't do all that with air campaign alone, you can destory the centrifuge or missile design bureau, but unless the overdriving factor behind it was gone as well (ie the regime) they would just rebuild them and have them operational again. Which means the issue we face is, if we are to go and try to achieve what we said as a strategic goal, we need at least a ground-based conventional invasion.
Which means Israel will want to push Hezbollah to fight in a conventional war, ala how we force the Iranians to fight a conventional war with us and systematically destroy their capability, the only way Hezbollah can survive this encounter is to go asymmetrical because if the IDF were to engage in their strategic objective, they would need to do it for a long haul, they can't just do hit and run strike anymore.
For us, depends on the overall war goal, if we are to just go in and take out the nuclear fuel and missile development, which mean leave anything else to the next admin (because it's going to take time to restart, by then Trump will be long gone) to achieve that, we don't need to control the entire Iran, all we need is to hit the Iranian at the site that we think they have the stuff. Which means if Iran doesn't want us to do that, they will have to face up conventionally. There won't be a point for Iran to fight asymmetrically against us, but of course, if what we want to do is to do this "permanently," then we will need to push for regime change, which means we are looking at another Afghanistan.
