Sixty-one percent of those questioned in a Quinnipiac survey conducted in late June and early July said that it was not in the national interest for the U.S. to be involved in the war in Syria. And nearly six in 10 said they opposed the U.S. sending military arms or supplies to the rebel forces fighting the regime of Syrian President Bashar al-Assad. Those findings were consistent with earlier surveys from Gallup, Pew Research Center, and CBS News/New York Times that were conducted in June. …

In May, a CNN/ORC Poll asked, “If the United States were able to present evidence that convinced you that the Syrian government has chemical weapons and has used them to kill civilians in that country, do you think the U.S. would or would not be justified in using military action against the Syrian government?”

Two thirds of those questioned answered yes, with three in 10 saying no.

An ABC News/Washington Post poll from last December had similar results, with more than six in 10 supporting military action Syria if it used chemical weapons against its people.
