Q6: Is “Freeze for freeze” (Iran freezing its nuclear program, in exchange for a freeze on new sanctions) a reasonable deal?

No. To demand that Iran cease an ongoing activity while our side ceases nothing and all existing sanctions remain in place—and continue to cause more damage to the Iranian economy—clearly would not be an equitable deal, and there is no way the Iranians would regard it as such. We are going to have to give something to get something.
