Israel has no force projection capabilities that would allow them to conduct an offensive ground attack against Iran.  That said, the same could be said for the Iranians.  In order to attack Israel in a ground war the Iranians would require the cooperation and consent of Iraq, Syria, and Jordan, and I doubt this would happen since Iran (Persia) has been a much bigger potential threat to those countries than Israel could ever be.  Theoretically Israel could launch an air strike against Iran, but this would be a massive undertaking, and would probably require the assistance of the United States.  An Isreali air attack would be a relatively small scale attack against specific targets in Iran.  I sincerely doubt that the Iranians could successfully repel such an attack.  The Iranians are completely incapable of launching an air strike on Israel without the assistance of Iraq and/or Syria, and even then I doubt they would be successful. 

 

Were the Iranians to launch a nuclear strike against Israel they would be obliterated........or at least Tehran and most of the major population centers in Iran would be.  The Iranians would probably also face massive airstrike (if not nuclear attacks) by the United States as well.  It would be suicide, but people with an apocalyptic world view may be willing to take the chance in order wipe Israel of the face of the Earth.

Iran is making a lot of missiles. The Iranians believe in conventional missiles. Not just for saturation but also to take out specific targets. They believe that their cluster warheads can take out airfields."

 

Mastering big powder propulsion is a technology that even Russians mastered only end of seventies.

We can suspect Iran managed to get help from Russian, former USSR republics and China, legally or not.But it is done.

Israel supplies Israeli-developed military technology to most of the world?s top militaries including the USA, India, and China. China's J10 fighter is thought to be modeled on Israel?s Lavi.,the Israeli developed Jet fight.

USA allow Israel  companies to compete on US internal market.Israeli-developed military technology is funded by USA as Lavi program was and ended when US removed aid.

In terms of MBTs, Israel possesses 1500 consisting entirely of the modern highly regarded Merkava. Iran has approx. 500 all obsolete models including the T 72. In front-line aircraft Israel has approximately 800 with more than 500 being upgraded F15s and F16s. Israel also possesses in air refueling capabilities. Iran has about 250 front-line combat aircraft consisting mostly of obsolete older US and Russian fighters.

And how you transport Merkava to Iran? (Israel has more than 1200 operational Merkava BTW).

Israel has about 250 operational combat aircraft (F15 and F16).

Other aircraft has reached their end of service life for years and have been discarded.Do you think Mirage, Kfir, A4 and Phantoms of sevnties or F15A are still all operationals? LOL

A combat fighter has a limited service life of about 30 years at most.

Israel has still a very capable air force but only few dozen could reach Iran via air refueling.

 

It has no known in air refueling capability.

Well, thet have.Supplied by USA and now updated in Iran.F14 were air refueled and Shah bought air refuelers.

Most of Iran fighter are obsolete but some upgraded indigeously of with Russia or Chinese components and subsystems.

Israel also is way ahead in production and use of UAVs and sells various models to many countries including Great Britain. There are other areas of military technology Israel is far more advanced than Iran.

 

However the danger is that Iran is slowly filling the gap in everyfields and gaining 100% autonomy in producing weapons.

In 2020 they will have advanced weapons in some key fields, ability to produce in numbers including aircrafts, and they will be damn dangerous by supplying their allies like Syria.

The problem of Israel fan boys like you is that you are so proud of Israel that you exagerate Israel capabilities by a magnitude, and do not see Iran enormous progress.

Israel has a big strategic problem and security concern with Iran since Iran is gaining strategic parity, building a massive local weapon industry even it will need still 1 or 2 decades to achieve maturity, and is far more robust and populated than Israel.

For my self Iran danger is not for Israel mainly.

They use Israel mainly to get arab street opinion, to maintain tenses in area, to destabilize arabs countries whom leadership support western nations.

Danger is for west europeans nations and USA who rely on gulf oil and Iran has make it clear they want westerners out of the Gulf area.

They can not use more than a small fraction of their air power against Iran while Iran has means to bomb them with IRBM and using terrorism and Hezbollah.
Now it is granted that Isreal has much more advanced military means.And no strategic depth.
