Critics of any pre-emptive strike against Iranian nuclear facilities rightly claim that Israel cannot totally destroy the Iranian nuclear program. But that misses the point.

How far away is the day when Israelis and Americans will wake up and realize that it is too late to stop Iran’s nuclear weapons program? This is not a new question. Seven years ago Jonathan Tobin writing in Commentary also asked, “Is it already too late to stop Iran?

Last week, I met with Israeli military, security and intelligence experts, and I asked if it is already too late to significantly affect the progress of the Iranian nuclear program with a pre-emptive strike, and the answer was always that it is not too late. But the caveat that followed was, the Americans can do it much more effectively than we can.

Critics of any pre-emptive strike against Iranian nuclear facilities rightly claim that Israel cannot totally destroy the Iranian nuclear program. But that misses the point.

Delaying the program five or 10 years, which would be the case with an Israeli strike, could be game changing, especially in conjunction with continued cyberattacks and escalating American sanctions that undermine the support for the regime by the Iranian people, who are increasingly becoming economically harmed and blaming it on the Mullahs and their corrupt cronies.

We know that before the 2015 JCPOA deal, Iran was already technically capable of reaching the crucial 20% uranium enrichment level, and was within a just a few months of amassing enough 90% uranium for a nuclear weapon, even using obsolete and unpredictable IR-1 centrifuges.

So the question to ask now is, how much have Iran’s nuclear capabilities advanced over the last four years since the beginning of the JCPOA? How much closer are they to a nuclear breakout?

We know that the agreement allowed Iran to continue to develop advanced centrifuges that can enrich weapons-grade material in a significantly shorter amount of time than the older IR-1 centrifuges, reducing the critical time to produce enough fissile material to just a few months. These advanced centrifuges are also much smaller and harder to detect.

Additionally, Iran never accepted the Additional Protocol, a nuclear addendum that allowed international inspectors to visit military sites where they would likely be developing nuclear missile warhead production.

Already last year, David Albright, president of the Institute for Science and International Security, estimated that Iran could enrich enough material for a bomb in eight to 10 months. The deal’s supporters claimed that the agreement would not allow Iran to enrich enough uranium for a nuclear weapon for one year during the length of the agreement, something that is already probably untrue.

After Israel’s revelation of Iran’s nuclear archive, we now know without doubt that Iran planned to build a nuclear weapon, and still has the information and capabilities to accomplish this. This is not Saddam Hussein all over again.

Even if international inspectors wanted to visit a military faculty, the JCPOA gives them a month’s time to comply, more than enough time to clear away any evidence.

THE DAY Iran passes the threshold for creating a nuclear weapon, everything will change for Israel, the Sunni Gulf states, Turkey, the US and Europe, and the world will be a much more dangerous place. A nuclear arms race will begin in the Sunni world, dramatically increasing the potential dangers of a nuclear conflict in the future.

So can Israel, this late in the game, still effectively strike the Iranian program? The answer is yes – but again, the US can do it better.

Iran has a plan to make Israel think twice before attacking. According to former national security adviser Yaakov Amidror, now a Senior Fellow at the Jerusalem Institute for Strategic Studies and a distinguished fellow at JINSA, Iran’s strategic plan – which is well underway – is to create a deterrence barrier around Israel, stretching from Lebanon to Syria to Iraq to the Gaza Strip, in order to threaten Israel with an overwhelming and devastating strike on its homeland, should Israel attack Iran’s nuclear facilities.

Is delaying their program five years worth the price Israel will pay if tens of thousands of missiles are unleashed, capable of hitting everywhere in the country, while the negative diplomatic fallout will be enormous, especially if Donald Trump is not US president?

Hillel Frisch of the Begin-Sadat Center for Strategic Studies wrote “In both word and deed, Israel is firmly committed to its redlines. The reddest of all is that Israel will not permit Syria to be turned into a forward base for direct Iranian operations and a manufacturing center for precision-guided missiles.”

Which means the noose will only tighten around Israel, as the Iranian operating bases in Syria over time will eventually look more like Hezbollah in Lebanon.

Yet when I ask the Israeli experts if Prime Minister Benjamin Netanyahu is the paper tiger that the Obama administration portrayed when a senior official called him chickens**t, the response was clear. If Bibi is convinced tomorrow is too late to stop a functioning Iranian nuclear weapon, he will indeed act today.

What will an Israeli attack on Iran look like?

Think out of the box. Not only cyberattacks and sophisticated strikes against known and presumed nuclear sites like Natanz, Fordow and the unnamed military sites conducting nuclear work, but targeting the lifeline of the Iranian economy – the port of Bandar Abbas, where almost all of Iranian commercial shipping trade transits, and Kharg Island, the location where Iran exports most of its fossil fuels.

An Israeli attack at Kharg or Bandar Abbas would make the impact of the current sanctions look like a popgun, and the survival of the regime would hang in the balance, as an economically devastated Iran will be imperiled from within.

If Israel does launch an attack on Iran, what would Israel look like the day after?

I remember visiting the North after the 2006 Second Lebanon War. Hospitals hit, hundreds of thousands of residents displaced to the South or living in steaming hot underground shelters and millions of Israelis throughout the country feeling vulnerable and angry.

Now imagine a hundred times worse, with the Dimona nuclear faculty in the South and Azrieli towers in central Tel Aviv in the crosshairs of Iran. The layers of Israel’s missile defense are remarkable but are incapable of stopping all the missiles heading for Israeli cities.

Time is not on Israel’s side, but when will tomorrow be too late?
