Israel is an asset to United States (and therefore world) security. American combat fighters do not have the opportunity to probe the Axis of Evil's defenses in battle situations, and America certainly receives full information regarding these sorties:
The Russians have sent technicians to upgrade Syria's air defense system after Israel foiled it using stealth technology to remain invisible during an airstrike.
The Israeli air force used a sophisticated electronic warfare system operated by F-15I jets and a fleet of specialist electronic warfare aircraft over the Mediterranean during the attack on a suspected nuclear facility near Dayr az-Zawr on September 6.
They transmitted signals that jammed the Russian-made radar and the Syrian army's communications.
Notably, the Israeli government finally admitted to the Syrian incursion today. I pointed out from the beginning that the denials were not plausible.
Unfortunately, Israel's political echelon just delayed further the purchase of American stealth fighter jets, due to lack of funds. This is the main reason why the economic strength that is an inevitable consequence of free-market reforms is essential for Israel.
On the bright side, half a billion dollars were found in the Israeli budget to fund Fatah directly and indirectly, Hamas.
