I just looked at a data comparison of regional military strengths, and the gap between Iran and Israel is indeed quite large. Iran has a population of 92.4 million, while Israel has only 9.5 million, but in terms of military spending, Iran's defense budget is $15.4 billion, and Israel's is $30.5 billion, with a completely different ratio.

Interestingly, although Iran has a larger population base, there are obvious differences in equipment and configuration. Iran has 1,713 tanks compared to Israel's 1,300, and the number of bombers is also Iran's 65,825 versus Israel's 35,985. But when it comes to air power, Israel has 611 fighter jets in reserve, while Iran only has 551.

In terms of personnel, Iran has 610k active military personnel, while Israel has only 415.4k. However, from a naval perspective, Israel's submarine fleet has 62 submarines, while Iran has only 107. Overall, although Iran's population advantage is obvious, the military strategies and equipment focus of the two countries are completely different, making direct comparisons difficult.
