The main reason is that Israel is materially supported by the West, so Westerners feel morally responsible for what it does.
It has little to do with whether the perpetrators are Jewish or not[1]. There were gigantic protests against the Iraq war, whose main perpetrators (e.g. Bush) were not Jewish.
1: I edited this from "nothing" to "little". I concede it might have something to do with anti-Semitism, because there is some non-zero group of people whose opposition to Israel is purely motivated by anti-Semitism, but I don't get the sense that they're the majority, at least among Westerners.
The current Syrian government is also supported by the west, just not to the same degree and not as publically. Myanmar is basically not mentioned at all in the Western press, nor Sudan or Libya or anywhere else war crimes are regularly taking place. I'd guess that the reason for Israel being in the media so much is that there are many more Palestinians and Jews than Rohingya or Burmese or Druze or Syrians in Western countries.
That’s not the reason. Almost certainly people feel a strong reaction, then when asked why it’s selective reach for a plausible answer. “Israel is supported by the west” is plausible.
What's this denial based on? Would you consider "Israel is part of the West" (rather than "supported by") to be more credible (and different enough to distinguish)?
