Israel hopes the United States will knock out Iran's underground nuclear site Fordow with its superior firepower but may try alone within days while military gains and global opinion allow, two Israeli security sources told Iran International.
The two sources still viewed joint action alongside the United States as the most likely scenario, within 48-72 hours at most.
An attack could be underway as early Friday night, the sources added, but Israel is also weighing going it alone to avoid losing the military advantage it has gained this week.
“In order for us to force Iran into concessions it would otherwise not make, and to bring it back to the negotiating table, this is the only way; we need the US to take action," an Israeli intelligence source told Iran International on condition of anonymity.
"We need Trump to do this within the next two to three days," one source added. "Trump is extremely unpredictable right now though, so anything could happen.”
Buried deep underground, the Fordow nuclear enrichment facility has remained untouched so far in the ongoing Israeli military campaign which appeared to take Iran by surprise in the early hours of last Friday morning.
Window closing
The window of opportunity to knock out the site was closing, the second Israeli security source said, and Israel had been planning for an attack for months.
“Until now the IDF (Israeli military) has opened up the flight path to Iran and the skies are open but that will be for a limited time, it can’t go on indefinitely,” he told Iran International on condition of anonymity.
“Therefore, if America decides to get involved, it has to be a decision made as fast as possible otherwise the opportunity will be missed.”
As the war begins to impact the global economy, including the soaring price of oil, the source said world powers could quickly lose patience with the conflict.
“There are economic issues at stake, so for example if oil prices spike, then these countries could be involved due to their own economic interests. So in general, America has to take this opportunity within 48-72 hours.”
The reach and strength of Israel's bombers are more limited compared to their American peers, making an attack on Fordow by Israeli forces alone more complex.
“Israel doesn’t have the heavy B-52 capabilities to drop a 14-ton bomb to penetrate the heart of the Iranian atomic sites that have to be destroyed,” the security source said.
Israel’s F-15s travel nearly 2,000 kilometers with far smaller payloads of around 400 kilograms, the source added. "Do the math. America could do that mission within a few days, but for us, it would be a much longer, more complex operation."
Destroying the Fordow enrichment facility requires a US military asset never been used in war, according to a report in the Wall Street Journal.
Known as the Massive Ordnance Penetrator, the GBU-57 is designed to tear through 200 feet of mountain rock before exploding. The United States has around 20, the newspaper reported, delivered via B-2 stealth bombers.
In the White House on Wednesday, Trump maintained studied ambiguity. “I may do it. I may not do it. I mean, nobody knows what I’m going to do,” he told reporters.
Iain Overton, the Executive Director of Action on Armed Violence, told Iran International that despite the heavy blows taken, Tehran could opt to fight on.
“Iran may lack parity in conventional military terms, but it possesses a distributed deterrent capability: armed proxies across the region, cyber warfare expertise, and a long-honed ideological machinery that frames death not as loss but as victory," he said.
"If the Ayatollah’s regime interprets US involvement as existential, it will not capitulate. It will escalate.”
