Interesting news today, Israel remains the only country on earth capable of freeing a spy in the USA convicted and serving a life sentence.

A complicated relationship.

It probably has something to do with Israel being very popular with wide swaths of the American public (particularly evangelical Christians), to such an extent that it's not terribly uncommon to hear American politicians praise Israel to garner more support from themselves.

Israel gladly accepts all the help it can from the US, but is well aware of the large support that American anti-zionist and pro-palestinian causes receive. They also don't trust certain administrations to always have their back, even if stated publicly.

In summary, Israel always has a bunker mentality of "us vs. the world". The US, while an ally, isn't immune from suspicion and active and aggressive spying efforts.
