How do you mean that?
It was the indelible two-thousand year old European anti-Semitism that resulted in the WWII Holocaust (I believe the Nazis needed the fertile soil of European anti-Semitism to make their Final Solution viable). The Holocaust resulted in 500,000 Jewish (approximate) survivors ("displaced people") that needed a place to live after the end of WWII. European anti-Semitism, I believe, really gave them nowhere to go. Britain solved the problem by allowing Israel to come into existence. No one wants these six million Israeli Jews today either. Israel is the only place these six, or so, million Israeli Jews can live today.
So, if one studies the history of Israel's survival ever since 1948, one sees the same nations that were the allies in WWII, at different times, helping Israel survive. Whether it's out of some guilt for not helping Jews in WWII, or more likely I believe, over the guilt/realization that all these countries allowed anti-Semitism to be very much part of the popular culture for centuries (which resulted in the fertile soil for the Final Solution to be viable), the western allies are not about to let Israel be a failed state.
Regardless, if there are countries today that would wipe Israel off the map, the western powers do remember that only in the mid-twentieth century Jews were considered excess baggage as
their own citizens by many people. In effect, I believe, all that monetary aid to Israel assuages some sensitive feelings, by the western powers, of their historical anti-Semitism.
