Just something that I've been thinking about - Israel buys a large percentage of its oil from Azerbaijan, and that oil sadly runs through turkey, but as the relationship between Israel and turkey keep deteriorating, and a conflict between the 2 might be closely rising, especially with the tension between Israel and the jihadist Syrian regime, which is a protectorate of turkey, Israel might crucially need another source for oil, and a free Iran might be the best option and partner for that crucial need.
Also turkey has an extremely powerful army, and another powerful ally in the region might be needed, especially if the US is unreliable.
