A poll that had input from more than 11,000 people in February found that about two-thirds of Americans worried that the US would become "engaged in a major war in the next four years."

The poll, carried out by NBC News and Survey Monkey, determined that 36% of Americans were very worried, 30% were worried, 25% not too worried, and only 8% were not worried at all. But when looked at along party lines, a stark divide emerged.

A whopping 88% of Democrats expressed worry over a major war. Only four in 10 Republicans felt the same way.

The US showed greater unity on the issue of alliances, with 62% supporting alliances even if that means compromising and 80% of respondents supporting NATO.

The partisan divide was alive and well, however, on the issue of the US's main geopolitical adversary, Russia. While 61% of Americans thought of Russia as unfriendly or as an enemy to the US, only 49% of Republicans felt that way compared with 76% of Democrats.

Seventy-three percent of Republicans ages 18 to 29, who grew up after the Cold War, thought of Russia as an ally or friend, while 69% of Republicans ages 65 and up thought of Russia as unfriendly or an enemy.
