@Walter Hinteler,
Back to the possible attack by Israel.
I suppose, it might start in a not to far future. Atleast, all is prepared by Israel to start it soon.
Israel really could have got from the Saudis the right for the Israeli air force flying through their airspace - the Saudis have various reasons, from historical ones over Arab-Persian dislike and different religious views to today's main power in the Muslim word.
Thus, Israel could use the new F-35.
A Dolphin-class submarine is already (after passing the Suez Channel recently) in that region as well: equipped (built in and donated by Germany) with four torpedo tubes which are capable of launching nuclear-armed Popeye Turbo cruise missiles. (They thus differ significantly from their "parents", the German 209-class.)
And since VP Biden said that Israel could determine for itself what they decide to do relative to Iran .... well, the big bang might come soon.
Seems, we can't have enough wars.
