The "deal" negotiated with Iran has many flaws (24 days till inspection, removing sanctions prior to proof of compliance, allowing continuing support of terrorist organizations such as Hammas, no true end to Irans nuclear program, no freedom for Americans held in Iranian jails, no end to Irans proclimations of "death to America" and stated goal of eliminating Israel, etc.)
The deal is not viable and gives the world nothing but an arms race in the middle east and at best 10 years till Iran has the bomb.
Step away and force Iran to sign a meaningful deal, even if sanctions or military actions are needed to get them to do so.
