Again, they recently had (or still have) the highest case per million rate in the world! Compare this to Palestine, with a vaccination rate of about 10% and roughly 1/40 of the cases per million. You could argue that Palestine is one big pocket of unvaccinated people. Why are the cases so much lower? And how would the situation in Israel be without vaccines? Worse than now or the same as in Palestine?

Different countries, different events, different cultures, etc.

There is also the problem of having a sense of security when there is a large vaccinated population which causes the vaccinated population to resume a regular life. Those who are not vaccinated are now exposed to more people in general.

Example, my wife and I prior to being fully vaccinated interacted with less than 10 people in the 1.5 years. We had everything delivered and had someone do our Costco shopping and drop it off at our doorstep. With us both fully vaccinated we go to Costco for our groceries and indirectly come in contact with probably 50 people in a single visit.
