The fragile ceasefire between Israel and Iran appeared to be holding on Wednesday after a rocky start, giving rise to cautious hope that it could lead to a long-term peace agreement even as Tehran insists it will not give up its nuclear program.The ceasefire took hold on Tuesday, the 12th day of the war between Israel and Iran, with each side initially accusing the other of violating it until the missiles, drones and bombs finally stopped.On Wednesday, U.S. President Donald Trump, who helped negotiate the ceasefire, told reporters at a NATO summit in the Netherlands that it was going “very well.”“They’re not going to have a bomb and they’re not going to enrich,” Trump said about Iran.Iran has insisted, however, that it will not give up its nuclear program and in a vote underscoring the tough path ahead, Iranian parliament agreed to fast-track a proposal that would effectively stop the country’s cooperation with the International Atomic Energy Agency, the Vienna-based U.N. watchdog that has been monitoring the Iranian nuclear program for years.Ahead of the vote, Iranian Parliament Speaker Mohammad Bagher Qalibaf criticized the IAEA for having “refused to even pretend to condemn the attack on Iran’s nuclear facilities” that were carried out by the United States on Sunday.“For this reason, the Atomic Energy Organization of Iran will suspend cooperation with the IAEA until security of nuclear facilities is ensured, and Iran’s peaceful nuclear program will move forward at a faster pace,” Qalibaf told lawmakers.In Vienna, IAEA Director General Rafael Mariano Grossi said he had already written to Iran to discuss resuming inspections of their nuclear facilities.Among other things, Iran claims to have moved its highly enriched uranium ahead of the American strikes and Grossi said his inspectors needed to re-assess the country’s stockpiles.“We need to return,” he said. “We need to engage.” Questions over effectiveness of the US strikes The American strikes hit three Iranian nuclear sites, which Trump said had “completely and fully obliterated” the country’s nuclear program.From Tehran, Iran’s Foreign Ministry spokesman, Esmail Baghaei, confirmed Sunday’s strikes by American B-2 bombers using bunker-buster bombs had caused significant damage.“Our nuclear installations have been badly damaged, that’s for sure,” he told Al Jazeera on Wednesday, while refusing to go into detail.He seemed to suggest Iran might not shut out IAEA inspectors for good, however, noting the bill before parliament only talks of suspending work with the agency, not ending it. But he also insisted Iran has the right to pursue a nuclear energy program.“Iran is determined to preserve that right under any circumstances,” he said.Trump’s special envoy to the Mideast, Steve Witkoff, said on Fox News late on Tuesday that Israel and the U.S. had now achieved their objective of “the total destruction of the enrichment capacity” in Iran, and Iran’s prerequisite for talks—that Israel end its campaign—had also been fulfilled.“The proof is in the pudding,” he said. “No one’s shooting at each other. It’s over.”At the NATO summit, when asked about a U.S. intelligence report that found Iran’s nuclear program has been set back only a few months, Trump scoffed and said it would at least take “years” to rebuild.Israeli military spokesman Brig. Gen. Effie Defrin said Wednesday his country’s assessment was also that Iran’s nuclear facilities had been “significantly damaged” and its nuclear program “set it back by years.”Grossi said he could not speculate on how bad the damage was but that Iran’s nuclear capabilities were well known.“The technical knowledge is there, and the industrial capacity is there,” he said. “That no one can deny, so we need to work together with them.” Hopes for a long-term agreement An Israeli official, speaking on condition of anonymity to discuss internal deliberations, said the ceasefire agreement with Iran amounted to “quiet for quiet,” with no further understandings about Iran’s nuclear program going ahead.In the Fox News interview, Witkoff said Trump is now looking to land “a comprehensive peace agreement that goes beyond even the ceasefire.”“We’re already talking to each other, not just directly, but also through interlocutors,” Witkoff said, adding that the conversations were promising and “we’re hopeful that we can have a long-term peace agreement.”However, Baghaei, the Iranian spokesman, said Washington had “torpedoed diplomacy” with its attacks on Iran’s nuclear sites, and that while Iran in principle was always open to talks, the country’s national security was the priority.“We have to make sure whether the other parties are really serious when they’re talking about diplomacy, or is it again part of their tactics to make more problems for the region and for my country,” he said.China, a permanent member of the U.N. Security Council and close Iranian partner, also weighed in on Wednesday, saying it hoped a “lasting and e
