U.S. Allies Trust the American Nuclear Umbrella, Even if They Hate Nuclear Weapons
Russia’s invasion of Ukraine has led to fears that it could snowball into a nuclear confrontation between Moscow and Washington. Against this backdrop, Morning Consult surveys show that the populaces of four of America’s most important non-nuclear-armed allies prefer living under an allied nuclear umbrella rather than obtaining their own weapons, and have negative views of nuclear weapons and global proliferation.
U.S. Allies Without Their Own Nukes Don’t Think They Would Improve Safety
Across the globe, few think building nuclear arsenals is a good idea
- Adults in Australia, Japan, Germany and Italy are more likely than not to think their countries do not need nuclear weapons, given that their allies have them. In Japan, these views are less firm, though the status quo was nonetheless favored by a large margin.
- In Spain, opinion is more evenly split: Despite their NATO membership, 36% support building a nuclear arsenal, compared with 31% who oppose doing so.
- Fewer than 1 in 7 adults in those same five major U.S.-allied countries, none of which have their own nuclear weapons, think the acquisition of such weapons would make the world a safer place, while majorities in each country think building nuclear weapons would either have no impact or make the world less safe.
U.S. allies strongly dislike nuclear weapons
Ever since the United States first unleashed the terrible power of nuclear weapons on Hiroshima and Nagasaki 77 years ago this month, America’s nuclear arsenal has undergirded its global strategic planning by extending protection to allies and deterring such foes as China and the Soviet Union through “mutually assured destruction.” Since the fall of the Iron Curtain, former Soviet bloc countries such as Poland and the Baltic states, who are under the U.S. nuclear umbrella by virtue of their NATO membership, have avoided the Russian invasions suffered by nonmembers Georgia and Ukraine, even if they are still frequently harassed by Moscow.
However, whatever security benefits American nuclear weapons provide for U.S. allies, their unimaginable destructive power and ability to permanently end or severely alter all life on Earth seems to outweigh their foreign policy utility in the global public imagination.
Major U.S. Allies Have Overwhelmingly Negative Views of Nuclear Weapons
At least two-thirds of adults in the United Kingdom, France, Italy, Spain, Germany, Japan and Australia have unfavorable views of nuclear weapons. In fact, only in France and the United Kingdom, both nuclear-armed states, are there not majorities with “very unfavorable” opinions of nuclear weapons — and even then just barely.
The data from Spain is particularly notable, given historic context. Spain formerly both hosted U.S. nuclear weapons on its soil and funded a weapons development program, but booted the American bombs and ditched the program prior to its 1982 accession to NATO. Ever since, Spain has refused to host nuclear weapons as a condition of its membership in NATO, a policy reaffirmed by a 1986 popular referendum, and Spain is generally thought to be one of NATO’s most nuclear-skeptical countries.
But contrary to common perception, Morning Consult data not only shows that Spaniards are more interested than their peers in other non-nuclear-armed U.S. allies in building nuclear weapons, they are less averse to them than adults in Germany, Italy or Japan.
Surveys conducted July 12-16, 2022, in the United Kingdom and Aug. 16-17, 2022, in remaining countries, among representative samples of 1,000 adults in each country, with unweighted margins of error of plus or minus 3 percentage points.
