Is the NATO weak against Russia? The recent Iran conflict might not have been fought by NATO, but it forced the military experts to analyse the power bloc's war preparedness. According to a media report, Russia could be ready to challenge NATO within years, making the lessons from Iran difficult to ignore. The conflict exposed serious vulnerabilities: dwindling ammunition stockpiles, strained air defence systems, underpowered naval forces, and growing political divisions within the alliance. As NATO strengthens ties with Ukraine and reassesses its military posture, the Iran conflict may ultimately serve as a wake-up call—forcing the alliance to confront a critical question: not whether it is watching global threats, but whether it is truly ready to face them.
