More Uncle Intel - Israeli Sub to Fire Missiles Toward Russia to Start WWIII

I have a hard time believing this one because, in a WWIII scenario Israel is likely on their own with an advisary on each border. Although they have a much more advanced military they most likely lose territory fighting a battle on all fronts, unless it goes nuclear. In that case most nation states will cease to exist in the traditional sense of the word.
I'm sure someone with more war games experience could explain this alot better but Israel losses if they have to take on the whole middle east by themselves and that's what would happen if WWIII starts.

I can not see a scenario in which Israel could benefit from starting a large scale conflict.

great movie to this day almost 38 years later.

You mean the United States right?
The liberty was passing intelligence to the Egyptians. It was under NSA control. It was off the coast of Israel, in the middle of a major war. The US was neutral in the 1967 war, so Israel would have ZERO incentive to attack a US warship. The US was secretly passing intel to Egypt because the US had major oil interests in the arab countries through ARAMCO.
But you don't do your research right?

When Israel does something it's blatantly obvious, like striking the Syrian Army in the middle of the Syrians fighting ISIS.

You mean a US sub that was sold to them since no middle eastern country builds anything
