Most in U.S. support defending Taiwan against China invasion: Survey

Washington, June 29 (CNA) A large majority of Americans support the United States militarily defending Taiwan should the latter face invasion or blockade by China, according a recent survey by the Ronald Reagan Presidential Foundation and Institute (RRPFI).

The RRPFI said that the survey, released on June 22, showed 75 percent of Americans believed a war between China and Taiwan would affect U.S. security and prosperity.

In addition, 70 percent of respondents supported the U.S. taking military actions to defend Taiwan if China were to invade or blockade the island, the RRPFI said.

Backing for military action is bipartisan, with 75 percent of Democrats and 70 percent of Republicans supporting such a response, according to the RRPFI survey.

Some of the top reasons compelling survey respondents more likely to support committing to defend Taiwan include: Taiwan is one of the world's largest producers of semiconductors (71 percent); defending Taiwan is critical for the defense of other allies, such as Japan, South Korea, and the Philippines (70 percent).

Other reasons include that if Taiwan is not defended, it will send a message to China and other adversaries that the U.S. is not willing to stand up for its friends (70 percent).

The RRPFI's latest survey also reveals Americans are showing increasing support for a stronger U.S. role in global affairs and a commitment to the U.S.' allies in the Middle East, Europe and Asia, the organization said in a news release.

The survey shows a sharp 24-point increase since 2022 in Americans who believe the U.S. should be more engaged and take the lead in international events, including majorities of Republicans (69 percent) and self-identified MAGA Republicans (73 percent).

At the top of the list of geopolitical concerns is Iran, with a supermajority of Americans (84 percent) who want to prevent the Islamic Republic from obtaining nuclear weapons, and a plurality (45 percent) who support Israel conducting targeted airstrikes against Iran's nuclear facilities.

"These results demonstrate Americans continue to believe in President Reagan's vision of 'peace through strength,'" said Roger Zakheim, director of the Ronald Reagan Institute.

"Across party lines, Americans see U.S. international leadership both as a strategic necessity and a moral obligation. They understand the United States cannot remain secure or prosperous by retreating from the world," Zakheim was quoted as saying in the RRPFI news release.

The survey was conducted between May 27 and June 2, 2025, by a bipartisan research team at Beacon Research and Shaw & Company Research, according to the RRPFI.

It is based on a sample size of 1,257 respondents reflecting the demographics of the country, including 478 telephone interviews, split between cell phones and landlines, and 779 online surveys, it added.
