Is Israel Really the Problem? Or Jihad?

[How weird is it that this man, utterly distraught, has not dropped his cigarettes?]

from today's New York Times -

ALEXANDRIA, Egypt (AP) — Christians clashed with Egyptian police in the northern city of Alexandria on Saturday, furious over an apparent suicide bombing against worshippers leaving a New Year's Mass at a church that killed at least 21 people. It was the worst violence against the country's Christian minority in a decade.

After the massacre of 58 Christians at a church in Baghdad in November, and the repeated bombings of crowded Shi'ite mosques in Iraq, the 'blame-Israel' narrative is wearing thin.

So why does Europe and leftists and many media liberals in the US cling to it? What answer comes to mind?
