A new poll shows half of Americans believe the United States is entering another Cold War with Russia.

The Gallup poll shows 50 percent believe another Cold War is coming, while 43 percent disagree.

During his speech in Belgium on Wednesday, President Obama said that Russia's incursion into Ukraine doesn't constitute a new Cold War and that the situation shouldn't be viewed in that context.

The same pollster showed that in 1991, toward the very end of the Cold War, 25 percent thought it would have to be litigated again.
