Two different passports, only carry the right one: easy. And unless US border police is checking any, potential, Iranian travel data the NSA collected I don't see the problem. Confidently telling those border police officers you've never been to Iran seems to be the trickiest part.

No it doesn’t. Israel doesn’t routinely ask you if you’ve been to Iran, if they did, you answer tru fully if you know what’s good for you. Same if you go to Saudi.

The US specifically asks you if you have travelled to those countries. You can either lie, and that’s a serious risk at being jailed, deported, banned from ever going again, and having issues going to other countries, or you can tell the truth.
