Why did JD Vance cancel his trip to Switzerland for US-Iran nuclear talks?

Vance canceled his trip because Iranian officials refused to attend the scheduled talks unless Israeli strikes on Iranian-backed Hezbollah militants in Lebanon ceased, as confirmed by three regional officials and a person familiar with the mediation efforts; the White House statement cited logistical unpredictability but omitted the Lebanon violence as the explicit reason, while insiders indicated Iran directly linked its participation to halting Israeli military action.

What condition did Iran set for resuming the nuclear negotiations with the U.S.?

Iran insisted that Israeli strikes on Iranian-backed Hezbollah militants in Lebanon must stop before the talks could proceed, according to multiple regional officials and a source familiar with the ongoing mediation, who spoke anonymously due to the sensitivity of the diplomatic efforts.
