General Discussion

Most of Irans aircraft are old. And they don't have any bombers. Most nations don't have bombers anymore. I think only the US, Russia, and China have dedicated strategic bombers now. It makes sense, modern air defenses make approaching and entering enemy airspace risky. The only bombers that are still going to drop a gravity nuke is a stealth one. And even those will probably just fire a standoff one weapon like a cruise missile unless you have total air supremacy or a bunch of ewar aircraft blinding everything.
