For a start Iran has China as a major ally.

The squeeze is already beginning on Iran’s oil exports — and guess which nation quietly reduced its purchases from Tehran this month. Why, that would be China, Iran’s supposed protector.
The Chinese cut their imports from Iran roughly in half for January, trimming 285,000 barrels per day from their average last year of about 550,000 barrels per day, according to Nat Kern, the publisher of Foreign Reports, a respected industry newsletter.
China has made big investments in Iran and won't see them destroyed.
China's investments in Iran won't be touched if they didn't build the nuclear enrichment plants. And they didn't.

In the mid-1990s, Washington put strong pressure on Beijing over an agreement signed between China and Iran in February 1993 to build two 300-MW light-water reactors in Iran, causing Beijing to back out of a profitable deal also. Nuclear cooperation between China and Iran came to a virtual standstill during the 1997-1998 timeframe.
Iran is also a big supplier of oil to China who won't risk having an oil shortage.
As illustrated, China has already cut their purchases of Iranian oil by 50%.
Russia is another, less powerful these days, ally as is Germany and France who supply goods to Iran.

Russia built for Iran its first nuclear power plant, then refused to sell to Tehran the anti-aircraft missiles to defend it.
A high-ranking Russian told reporters in Moscow on Tuesday that it “remains unproven” that there is a military component to Iran’s nuclear program.
On the other hand, he added, Tehran’s decision to enrich uranium violates international resolutions designed to keep Iran from acquiring a nuclear bomb.

This article outlines the history of Iran's nuclear program, from the beginning with US backing, up to the present. On a side-note, Iran recently announced triumphantly that they were one of the first signatories to the nuclear non-proliferation treaty. They were. In 1970. Under the Shah of Iran. But the press eats that stuff up and ignores the back story.
Israel will bomb the nuclear plants and enrichment facilities that Iran has built. Russia built one of the plants, but as noted, has distanced themselves from Iran. Oil won't be threatened, Israel has no need to bomb Iran's oil-production facilities or destroy it as a country.
I do not think France or Germany will seriously stop Israel from doing whatever it wants to do vis-a-vis Iran.
