I would actually say that North America is *the* safest area in the world to be Jewish, though I do get the "safety in numbers" argument for Israel. Europe is also mostly not bad, most of the time.
The way I would put it is that the US is the safest place to be a Jew while Israel is the most secure.
We might be historically safe here, but we're also keenly aware that we're always one bad election from not being safe - not just on a national level, but on a city-wide or state-wide election level. Things can go downhill very quickly - Brandon Johnson's election in Chicago essentially turning the place into a safe zone for the most extreme pro-Palestinian protests is a mild example, while Mark Robinson potentially becoming Governor of North Carolina is a more extreme one.
