Iraq dominated the headlines throughout the fall of 2002 and into the winter of 2003. Public opinion on the wisdom of war, however, stabilized relatively early and slightly in favor of war. Gallup found that from August 2002 through early March 2003 the share of Americans favoring war hovered in a relatively narrow range between a low of 52 percent and a high of 59 percent. By contrast, the share of the public opposed to war fluctuated between 35 percent and 43 percent.
Looks like Americans are even more happy with murdering people if its done by a puppet.
So the 70% is combining “fully justified” and “partially justified,” with the only other options being “not at all justified” or “not sure.” There’s no option for like “mostly unjustified” so lots of people who both sides the issue - or even favor Palestine! - are likely to say “partially justified,” which is a very broad and vague statement.
Another headline you could write from this poll: “Only 27% of young people consider Israel’s response justified - compared to 81% of seniors,” or “50% of Americans think Israel’s response was justified.”
Polls are, as always, fake.
