I think the government of the time is unlikely to go straight to nukes but you might see some sudden fatalities in the higher ranks of the Nazi hierarchy. Their also going to seek to get as many Jews out of Europe and into Israel as they can. Which for those Jews outside the USSR and Germany could be fairly easy. At this date possibly not too difficult inside Germany as Hitler is only just gaining power. There will also be people arguing for the occupation of at least west Jerusalem and especially the Wailing Wall. Up time foreign diplomats will be useful here but how much would those be listened to by the corresponding down-time governments, at least in the short term.
They will have two basic issues:
a) Technically their occupying land which is a good chunk of the British mandated Palestine territory which is going to cause a lot of confusion and probably conflict, at least on a low level. Israel can win any such clash, at least in the short/medium term but their best bet is to try and sort out a deal with Britain and link up with as many other democratic states as it can. Might see an attempt to link up with the US, France and Czechoslovakia among others.
b) They have a powerful military and advanced technology but their army is very much a reserve one, which they can't keep mobilized for long at anything like full strength. Plus how much of that military can they support and maintain without any contact with the 1967 US?
Also with a short time span ISOL there's going to be the issue that many UTers will have younger versions of themselves already alive in 1933 - along with many relatives they know won't make May 1945
which is going to be a huge incentive to do something.
As the Nazi regime have just been in power for a few months since 30 January 1933 so a lot of the regulations of letting Jews leave Germany may not be in place - like stripping them of their money etc.
Regarding Jerusalem that would be occupation of the Old Town which happened during the 6-day War 5-10 June 1967.
The British and French probably won't spend much time listening to the Israeli state and tbe British being in two minds on what to do - turn a blind eye and leave the Palestinian troubles to them or take political action as not may be seen as leniency regarding a Mandate and may have repercussions in the Colonies. Lt. Wingate is going to find another place to kill peoples.
Both Nations may claim that their populations is weary of war and not ready to re-armament. The ISOT'ed ambassadors face a challenge here though their documented tales of European and world wide experiences of 1933 to 1967 may be of certain interest to the British and French - and Americans. Will the Soviet Ambassador go to the Kremlin? - the effect on Stalin will be intersting and the Purges may happen early.
Israel had a working Nuclear Plant since 1963 so have nukes though the great update of 1968 is a couple of years into the future. Also the Mirage III Blueprints haven't been obtained yet but then the IAF haven't suffered the losses of the Six Day's War.
Israel had made connections that have been severed - Iran of the Shah, South Africa and a number of African states not to mention USA, France and West Germany! Trade anti-biotics and agricultural advances will be a huge sell. Computing perhaps - if not the Israelis decide to keep the advances to themselves and let the rest go the long slog.
Generally the Israelis will be adaptive to this new old World and Persia - Imperial Iran may experience a hand in uplift if only to provide Israel with a local ally things come to a head with the rest of the ME.
Perhaps King Farouk will get a helping hand too if only to provide for a possibly more peacefull future - the Jordanian experience will count.
Also without the Soviet interference in the ME things will be much different though the Soviet Ambassador may view this as his steppingstone to Stalin's inner circle.
a) I'd guess the British may end up citing Divine intervention in their leaving Palestine to itself - of course there will be some problems regarding the Jerusalem Old Town which will have to worked out. Think Churchill will be elated that Britain may have acquired a possible Ally against Herr. Hitler. Praise of Dowding's Chain Home line and proof of its effectiveness and an upgrade or two may win the British as well as a nudge to the French.
b) Supply of spare parts and ammunition will be a problem though for some important hits on the Nazi's they'll be able to go. (Czechoslovakia will be the natural supplier to turn to)
Think Italy ITTL will be asked not to pass the Race-laws of 1938 as that would a terrible mistake that Il Duce won't survive.
Basically I'm not certain that Britain and France can be talked into a pre-emptive war but resisting actively the Nazi occupation of the Rhineland will be a tremendous set-back for Hitler.
which is going to be a huge incentive to do something.
