I suspect that lot of what Yossi Gurvitz says applies to attitudes in Britain and Europe:
“Last Thursday, a special UN commission on Syria found that the Assad regime is committing crimes against humanity, and that senior regime officials are participants in these crimes. The commission was significantly limited in its ability to report on events, as the regime denied it entry into Syria, and it had to rely on the testimonies of refugees. Even so, it is important to take its conclusions seriously: in several previous cases, the first testimonies about crimes against humanity came from refugees.
The refugees supply us with only a partial view, yet they indicate a terrible desolation, thousands of casualties, the systematic use of rape as a tool of terror, and prevalent torture. The number of civilians massacred by the regime in the last year is estimated in the many thousands – many more, for instance, than the number killed by the IDF during the Second Intifada. Naturally, the precise number is not known, but an opposition site that is considered reputable cites 8,791 dead; another site, which also furnishes a map of the atrocities, estimates the number of dead at 9,236. These numbers are updated to the time of writing of this post, and both of them reflect only the known dead – people identified by others. It’s very probable that there are hundreds more, unrecognized.”
