No world titles for UK, NZ, US, Canada and Oz?

My prediction: plenty of no shows blamed on a breakdown of negotiations about teams bringing their own security. 

You've misunderstood their ruling entirely.  It doesn't apply to all countries.  It will only be applied to countries that think Israel act disgracefully as a state. 
The issue with Malaysia panned out in all the sailing press (even Y&Y) exactly the same as it does with every issue that concerns Israel.  Whilst Malaysia's postition was, at best, tricky to defend, no one from the press at all even considered doing a proper interview sitting down with the organising authorities and getting their full side of events.  Everyone got Israel's version of events, but all we got from the other side was apparently some person overhead someone else say it was maybe done for political reasons..... yeah great objective reporting, well done. 
It's amazing how whenever Israel claims victimisation, no one does a full proper investigation of the other side's story.  Obviously Sailing Anarchy were the worst and most disgraceful on this, but they're American and extreme pro Israel, anti-muslim, with about as much objectivity as the british tabloid press, so that's to be expected. 
Several nationalities aren't allowed to travel to Israel, and if a championship were held there, wouldn't kick up a fuss because they wouldn't have to be denied entry as they'd be too sh*t scared of going there anyway..... but that wasn't mentioned in Y&Y or anywhere else either.  You know, because no one bothered to ask. 

This ruling has nothing to do with equality, and is exactly the knee jerk reaction you suggest it might be.  All they're worried about is, can those "other" nations stop us and our friends coming over? 

I see that Oman has had to give up holding the Youth Worlds because ISAF's new policy that demands that athletes of all nations must be treated equally under national laws and immigration policies; "the Summit agreed that for all competitions taking place under the auspices of an International Federation or National Olympic Committee or their continental or regional associations, it has to be ensured that all athletes from all their members can enter a country to compete and are treated equally. It was agreed that should this rule not be respected, the event in question cannot serve as a qualification event for the Olympic Games or any other championship."
