Israel is not really an ally. They routinely spy on the US, and according the the CIA, spy on us as aggressively as the Chinese and Russians do. During the Cold war, they used intel as a bargaining chip and passed classified material to the Soviets. Their nuclear program was started primarily with stolen radioactive material that they exfiltrated from the US. These stories go on and on and on, and they're just the ones we know about. Jonathan Pollard was hardly the only spy, but it was the most high profile.
It's naive to call them an ally. It's an extremely complicated relationship, made more toxic by the extreme power that AIPAC holds over our politicians. Every president since LBJ has been duped, outwitted and embarrassed by Israel. Frenemy would be more accurate.
The USA spies all the time on everybody so by your own def they should be not really an ally of anybody.
