Israel lets Iran know it is vulnerable

Jerusalem Post:

Two Israeli F-35 fighter jets entered Iranian airspace over the past month, Kuwaiti newspaper Al-Jarida reported on Thursday. The act is a signal of heightened regional tensions, especially in light of recent Israeli military attacks in Syria, including against Iranian bases in the country.

Sources quoted in Al-Jarida stated that two stealth fighters flew over Syrian and Iraqi airspace to reach Iran, and even targeted locations in the Iranian cities Bandar Abbas, Esfahan and Shiraz.

The report states that the two fighter jets, among the most advanced in the world, circled at high altitude above Persian Gulf sites suspected of being associated with the Iranian nuclear program.

It also states that the two jets went undetected by radar, including by the Russian radar system located in Syria. The source refused to confirm if the operation was undertaken in coordination with the US army, which has recently conducted joint exercises with the IDF.

The source added that the seven F-35 fighters in active service in the IAF have conducted a number of missions in Syria and on the Lebanese-Syrian border. He underlined that the fighter jets can travel from Israel to Iran twice without refueling.

Iran has nothing remotely comparable to the F-35.  It is still using F-4's bought from the US before the revolution that are patched together with stolen parts.  The Israelis also have a history of defeating the Russian radar system.
