Found this on a website:
Three weeks ago the US Defence Security Cooperation Agency (DSCA) published a notice, as it is legally required to do, announcing that Israel has ordered massive quantities of various fuels suitable for military use, and in the case of the order for JP-8 jet fuel, suitable only for military use.
The massive order is valued at some $2 billion and, as well as the 284 million gallons (1.075 billion litres) of JP-8 jet fuel, the order also includes 60 million gallons (227 million litres) of unleaded gasoline and 100 million gallons (378 million litres) of diesel fuel.
Conclusion: They are preparing for something.
You don't buy 2 billion $ worth of gas for nothing.
The shelf life of JP-8 is about 6-8 months...
So war it is within that timeframe.
That's quite a bit of fuel for a military the size of Israel.
