The IISS figures on Israel's military strength are wrong because the do not include the 230,000 18-21 year olds doing compulsory military service.

Thus Israel's military comprises:

1. ~180k full time professionals;
2. 230k compulsory service
3. 360k "rapid reaction" reservists (who were called up, equipped and battle ready within 2 weeks, something that took Russia 6-9 months) many of whom are now battled hardened from combat in Gaza.
4. Another 3M+ uncalled reserves who did compulsory military service but have not maintained active reserve status.

Thus Israel has 800k battle hardened, highly motivated troops with the best military tech in the world.

I've published a detailed post on this

Even if facing Turkey and Iran's military on a theoretical balanced battlefield Israel would wipe the floor. Iran has no modern tanks, aircraft, mobile artillery or anything needed to fight modern high intensity warfare. Turkey's best tanks (Leopard II) are proving very poor in the battlefields of Ukraine and in Turkey's own advances in Syria.
They are no match for Israel's tanks. Turkey's airforce is also not up to the standards of the IAF. Its troops have no serious combat experience.

Turkey does not have any of the critical high tech capabilities that are creating the IDF's historic overmatch in Gaza (Trophy APS, integrated sensor weapon fusion, AI targeting, numerous unique high tech systems such as Iron Sting mortars, SMASH personal weapon targeting (general infantry can easily shoot down drones and other difficult targets better than a trained sniper).

Of course there is no way for Iran or Turkey to even get their troops anywhere near Israel to fight in the first place. Turkey would have to fight its way through hostile Syrian territory where it is already bogged down. Iran would have to cross Iraq and Syria and has no mobile armoured force capable of this.

In contrast, Israel does have large, extremely powerful, mobile armoured forces that could invade Iran or certainly slaughter lightly armed Iranian troops attempting to move towards Israel.
