At a defence level, Israel and the US are as close as ever.

But the personal relationship between Israeli Prime Minister Binyamin Netanyahu and US President Barack Obama has always been described as uncomfortable, even tense.

One of the main reasons for this is Iran. Israel’s rhetoric against Iran has been increasing. There’s constant speculation it’s preparing to attack Iran.

But the US wants more time for diplomacy to work. It’s sent envoys, like Defence Secretary Leon Panetta to Israel with the message, do not launch a unilateral strike.
