Could MCU Iron Man Survive A Nuke?

Depends on yield. He should be able to tank the smaller tactical nukes

@baalhaddad: We saw then when it hit him the first time, it did not break anything on his armor, then it slammed him into the ground and he came a bit later unscratched, script also makes no mention of him being knocked out irrc, like it does in EG when Thor hit him, further supporting this point, it was also said in one video that Raj posted that meteor drove him beneath the surface/crust of a planet, which could explain why it took him some time to get back.
