No, no, and no.
Modern airforce is not just about the jets. Way, way more than that. People might benefit from the India-Pakistan May 2025 conflict. First time in human history, so many advanced gadgets, jets, satellites, EW, strategies were utilized between two peer-powers with a lot of preparations, training on both sides. IF Iran had invested in similar setup decades ago, then, maybe it would have helped otherwise their jets would be destroyed on the ground!
I believe Iran made right approach: Ballistic missiles in large numbers AND in investing in the proxies right next to Israel. They need to find a replacement for the lost proxies. And fast.
