A Gallup poll shows that support among Americans for Israel during the Gaza Strip conflict is divided, and is low among younger Americans.

The poll posted on the pollster’s website Thursday showed a statistical dead heat between those who believe Israel’s actions against Hamas are justified, 42 percent, and those who believe they are unjustified, 39 percent. The difference was within the poll’s margin of error of four percentage points.

Reactions to Hamas were lopsided, with 70 percent calling the group’s actions unjustified and just 11 percent describing them as justified.

Older Americans were much likelier to say Israel’s actions were justified: 55 percent of those over 65; 53 percent of those between 50 and 64; 36 percent of those 30-49 and just 25 percent of those 18-29.

There were other dramatic differences in how subgroups measured support for Israel, with 65 percent of Republicans calling Israel’s actions justified and just 31 percent of Democrats and 36 percent of Independents saying they were justified; 50 percent of whites said Israel was justified, while just 25 percent of non-whites agreed with that characterization; 51 percent of men agreed and 33 percent of women.

The poll was based on 1,018 phone interviews conducted on July 22-23.

Israel launched Operation Protective Edge on July 8 after an intensification of rocket fire from the Gaza Strip. More than 820 Palestinians, most of them civilians, have reportedly been killed since then, as have 36 Israelis, including 33 troops.
