In parts of internet I cannot verify, there is still a lot of talk, mostly rumors, that Iran has no intention of signing anything today.
At least some people in Iran are claiming that Trump made the whole thing up. There is no plan to sign a deal on Trump's birthday.
Trump has lost his mind over his stupid 'deal'. He is cursing Israel, coddling Iran, and making up facts to suit his megalomaniacal delusions.
Regardless of what fantasies Trump has dreamed up in his delusional fevered mind, his deal will not change a goddam thing.
Deal or no deal, tomorrow everything will be exactly the same as it is today, exactly the same as it has been for almost 50 years.
