The American public has grown more supportive of the US fight against the Islamic State group, with nearly two-thirds now backing the air campaign against the jihadists, according to a survey released Tuesday.

About twice as many approve (63 percent) as disapprove (30 percent) of the military campaign against the IS group in Iraq and Syria, a national survey carried out by the Pew Research Center found.

Those numbers are compared to 57 percent for and 33 percent against in October.

More divisive is the possibility of sending US ground troops to the region.

About as many would favor (47 percent) such a move, compared to 49 percent who oppose sending US ground troops.

Four months ago, 39 percent favored the idea while 55 percent were against.

The survey also found broad support for the US government’s policy of not paying ransoms for hostages, with 70 percent in favor and 25 percent against.

The remainder said they didn’t know.

The public appeared divided over whether “using overwhelming military force is the best way to defeat terrorism around the world,” Pew said.

Support for the US military air campaign against Islamic State militants in Iraq and Syria is split by gender and political affiliation.

More Republicans (70 percent) than Democrats (58 percent) approve of the campaign, and more men are in favor it (70 percent) than women (56 percent).

However, the public is skeptical about the effectiveness of the US campaign against the IS group. Fifty-eight percent said the military campaign was not going well.

Pew polled 1,504 adults between February 18 and 22.
