About half of registered voters — 53% — oppose U.S. military action against Iran, according to a new Quinnipiac Poll conducted over the weekend. Only 4 in 10 support it, and about 1 in 10 are uncertain. A new Ipsos poll also found more disapprove than approve of the strikes.

That’s similar to the results of text message snap polls from The Washington Post and CNN, both conducted shortly after the joint U.S.-Israel attacks began, which also indicated that more Americans rejected the military action than embraced it.

A recent Fox News poll found opinions more evenly divided: Half of registered voters approved of the U.S. military action, while half disapproved.

Several of the recent polls show a majority of Americans believe the Trump administration has not provided a clear explanation of the reasons behind the military strikes, and there are some divisions about whether Iran truly posed an “imminent and direct threat” to the United States, as the White House has said.

Most voters in the Quinnipiac poll — 55% — said they did not believe Iran posed an “imminent military threat” to the U.S. before the current military action. On the other hand, about 6 in 10 registered voters in the Fox News poll said Iran poses a “real national security threat,” and a recent AP-NORC poll found about half of U.S. adults were highly concerned that Iran’s nuclear program posed a direct threat to the U.S.
