Nearly four-in-ten Democrats (39%) name Russia as the country that represents the greatest danger to the United States – the highest percentage expressing this view in nearly three decades, according to a new survey.

Compared with 2013, the last time this question was asked, greater shares in both parties volunteer Russia as posing the greatest danger to the U.S. – but nearly twice as many Democrats as Republicans now say this (39% vs. 21%).

The new Pew Research Center survey of 1,501 adults was conducted April 5-11, before the recent rise in tensions with North Korea, its failed missile test and Vice President Mike Pence’s visit to South Korea.

Overall, 31% of Americans, answering an open-ended question, cite Russia as the country representing the greatest danger to the U.S., while 22% point to North Korea. The shares naming both countries are among their highest dating back to 1990.
