Dr. A.S. Podi Izzy, an expert on international affairs at Alma Tabthai University:
When the Chinese and Americans negotiated and reached an agreement in the early 1970s, China already had nuclear weapons.
An attack on Iran is being gradually normalized, just as attacks on Gaza were normalized, because for now we do not have absolute or partial deterrence.
America did not have, and still does not have, a military option against China, Russia, India, North Korea, Pakistan, or other nuclear-armed states. A war lasting several days could break out, as happened between India and Pakistan, but it would have to end quickly because of the possibility of nuclear war.
