Trump says he’s going to end it in one day. There is no way negotiation could end it in one day. Even if we unilaterally cut off aid, that would not do it in one day. Even if he threatened to drop the the abomb, that would not do it in one day. The only way I can see that he could end it in one day is by actually dropping the abomb.
I don’t think it was meant to be taken literally as one day.
