Is the United States declining as a military power? According to a recent Gallup poll, Americans are evenly split on the issue.

The survey asked responders whether they believed the United States was “No.1 in the world militarily.” A similar question in February 2015 reported that 59 percent of Americans were confident that the United States was a powerful military force. Now, only 49 percent are so sure.

Gallup has monitored American perceptions of U.S. military power for 23 years, but public opinion has never dipped this low. If this trend continues, the amount of citizens who doubt the country’s military prowess may increase above 50 percent for the first time.

What caused the public’s perception of the U.S. military to change in the past year? Gallup believes the answer is two-fold:

The 10-point drop in the percentage of Americans who believe the U.S. is the No. 1 military power in the world may reflect worries about international terrorism, which the public views as the most critical international threat the nation faces. It may also reflect the discussion of the military and defense in the current presidential election campaign.

The threat of ISIS and the constant discussion of military weakness at presidential primary debates is enflaming worries that the U.S. military isn’t up to snuff.

However, the U.S. remains the world’s greatest military power by any metric you try. Military spending. Advanced technology. Manpower. Worldwide bases. International alliances. We’ve got it all.

Gallup did find that 37 percent of Americans believe that the military isn’t getting enough funding. This percent jumps to 66 percent among Republicans and drops to 20 percent of Democrats.
