https://www.wsj.com/articles/allies-worry-over-u-s-public-opinion-11551741006There is no more important question in world politics than this: Will U.S. public opinion continue to support an active and strategically focused foreign policy? During the Cold War and for 25 years after, there was rarely any doubt. While Americans argued—sometimes bitterly—over the country’s overseas priorities, there was a broad consensus in both parties that sustained engagement was necessary to protect U.S. interests.
That consensus is more fragile today. Questions about the reliability of American commitments keep the lights burning late in foreign and defense ministries around the world. Secretary of State Mike Pompeo insists, as he said in Manila last week, that a Chinese attack on Philippine forces or territory in the South China Sea would activate Article 4 of the U.S.-Philippine Mutual Defense Treaty. But will the American people honor the check that Mr. Pompeo has written on their behalf?
The best answer appears to be “maybe.” A recent poll from the Chicago Council on Global Affairs found that 70% of Americans want the U.S. to take an “active part” in world affairs in the abstract. But in a 2018 Pew survey, only 32% said limiting China’s power should be an important long-term foreign-policy priority for the U.S.
Similarly, while a strong majority of Americans support membership in the North Atlantic Treaty Organization, just over half of Americans would support military action in response to a hypothetical Russian invasion of Estonia, according to a recent Eurasia Group Foundation survey. The Kremlin studies such poll results carefully, and so do NATO allies on Russia’s borders.
