Fifty-seven percent of Americans believe Israel is justified in taking military action against Hamas in Gaza, a CNN poll revealed Monday.

The survey showed that 25% of respondents believed action was not justified, and 19% had no opinion.

During operation Cast Lead in 2009, 63% of respondents to the same question supported Israeli action, while 31% opposed and 6% had no opinion.

In general, 59% said their sympathies were with the Israelis, and only 13% with the Palestinians.

The poll, conducted from November 16-18, sampled 1,023 adults and had a margin of error of 3%.
