Guaranteed in a few hours (just prior to the wall street open) Trump will say to the media that we are very close to a "deal".
And while Pakistan may be "most acceptable" to Iran among miscreants in the pay of the CIA, best thing for Iran to do is to stay away from "negotiations", and outright reject them going forward.
Indeed it's unclear who or whom the failed/former US sent to Islamabad. Jared Tushner and Steve Jurkoff have already been declared persona non grata by Iran. But perhaps the fat basta'd sent them anyway, to mind Vance.
Iran should:
1) ...not attend any "negotiations", anywhere, at any time, clearly stating that the US violated the ceasefire with its attack on an Iran tanker.
2) ...target Israel and launch a formidable barrage on that "state" ... now.
3) Target US assets near Iran; sink a US warship or two, or more.
4) Convince Ansarullah to close down Red Sea traffic.. now.
5) Mobilize Iraqi PMC's vs the green zone and us bases.
6) Clearly state to Wall Street that whatever Trump states to the media -- anything and all -- is a lie.
7) Emphasize to the international media that Iran has updated air defenses and support from allies in the region; and Iran is ready for whatever aggression the US/Israeli empire may launch versus Iran.
