S enior Israeli officials are acknowledging that some enriched uranium may have survived the powerful U.S. strikes on Iran's key nuclear sites last month.

What many have called a "fragile" ceasefire between Israel and Iran remains in place following nearly two weeks of missile strikes, which included the U.S. dropping "bunker-busting" bombs on Iran's three nuclear sites. But questions remain about how much damage the operation actually did.

The seemingly contradictory reports on the success of the US strike on Iran—with the White House claiming “obliteration” and a leaked intel assessment suggesting a setback of only “months”—may both be rooted in the same intelligence.

Pentagon reports Iran's nuclear facilities were "completely obliterated" in June strikes, offering a more optimistic assessment than earlier estimates while Iran acknowledges damage.

Thus, Europe will continue to pay close attention to Iran’s nuclear program. But, constrained by poor relations with Tehran and its internal divisions on the Middle East, it is unlikely that it will carve out a major role on the nuclear dossier as long as Trump is in office.

The process of uranium enrichment increases the concentration of U-235, an isotope that can sustain a nuclear chain reaction. Beginning in 2006, the U.N. Security Council called on Iran to suspend all uranium enrichment, but it endorsed the JCPOA on July 20, 2015.

We’re thinking probably closer to two years — like degraded their program by two years,” Pentagon spokesperson Sean Parnell said Wednesday.

President Donald Trump said on Friday that Iran had not agreed to inspections of its nuclear program or to give up enriching uranium.

Israeli Prime Minister Benjamin Netanyahu claims Iran will not pursue nuclear weapons following U.S. and Israeli strikes, stating Tehran is afraid after feeling "the might of America and Israel."

Opinion: Analysts will need more intelligence from more sources to make a confident judgment about the effects on Fordo and Iran’s broader nuclear efforts.

The United Kingdom, France and Germany have agreed to restore tough U.N. sanctions on Iran by the end of August if there has been no concrete progress on a nuclear deal, two European diplomats said Tuesday.
