Nearly two-thirds of Americans fear that the U.S. will soon enter another war, according to an online poll.
"All in all, how worried are you that you that the United States will become engaged in a major war in the next four years?" the NBC/SurveyMonkey poll asked respondents.
The poll found that 36 percent of respondents were "very worried" the U.S. will enter another war, while 30 percent were "somewhat worried."
Meanwhile, only 25 percent were "not too worried" and just 8 percent were "not at all worried."

The worrying is mainly from Democrats; about 88 percent of Democrats are worried that the U.S. will plunge into another war, compared to the 40 percent of Republicans who responded the same way.
During the administration of former President Barack Obama, the U.S. engaged in military action in seven countries including Libya, Pakistan, Somalia and Yemen, in addition to the ongoing wars in Iraq and Afghanistan, according to The New York Times.
The anxiety and uncertainty expressed by the poll's respondents perhaps reflect current President Donald Trump's foreign policy agenda, which his administration has still yet to outline in any real detail. While Trump was critical of the Iraq War during his 2016 presidential campaign, he has also been hawkish on Iran.
Unnamed Pentagon officials told CNN that one option they plan to give Trump on Syria is to deploy more ground troops than already sent by Obama.

Meanwhile, Defense Secretary James Mattis warned NATO countries that they must pay more for their military preparedness, as U.S. taxpayers can no longer foot the majority of the bill.
"I owe it to you all to give you clarity on the political reality in the United States and to state the fair demand from my country’s people in concrete terms," Mattis told NATO leaders in Brussels, according to ABC News."America will meet its responsibilities, but if your nations do not want to see America moderate its commitment to the alliance, each of your capitals needs to show its support for our common defense."
He added: "No longer can the American taxpayer carry a disproportionate share of the defense of Western values. Americans cannot care more for your children’s security than you do. Disregard for military readiness demonstrates a lack of respect for ourselves, for the alliance and for the freedoms we inherited, which are now clearly threatened."
