Republican Cracks Could Weaken Trump's Hand Against Xi

A vote in Congress might have revealed more than lawmakers intended—and Xi Jinping is likely taking notes.

After Israeli-U.S. strikes on Iran, both chambers of Congress voted on a War Powers Resolution to halt Trump's military action. The measure failed, with nearly all Republicans voting against it and publicly backing the administration. But beneath this display of party unity, a different story is emerging: growing private concerns among GOP lawmakers about America's latest military engagement.

As Trump prepares to meet with the Chinese president—where Taiwan will almost certainly be discussed—these underlying Republican attitudes toward military involvement abroad could significantly shape his negotiating position.

The Visible Unity, The Hidden Doubts

Senator Rand Paul was the lone Republican to support the resolution in the Senate, but his isolation may be more apparent than real. As a prominent voice of America's New Right, Paul has long advocated for foreign policy restraint. His concerns, however, are quietly shared by others in the Republican caucus.

Senator Susan Collins warned that the Trump administration must keep lawmakers "fully briefed on developments," while Senator Lisa Murkowski expressed being "troubled by the lack of a clear endgame." In the House, only Representatives Thomas Massie and Warren Davidson publicly supported the resolution, though other Republicans reportedly harbor similar concerns privately.

This pattern reflects a broader historical trend: support for military action typically surges early but fades over time. The Iraq War offers a telling precedent—overwhelming initial support collapsed as the conflict dragged on. Many Republicans remain wary after the "forever wars" in Iraq and Afghanistan, and Trump himself has acknowledged the Iran conflict could last weeks.

The Politics of Language

Republican discomfort is evident in how they describe the conflict. House Speaker Mike Johnson calls it an "operation," while Senator Josh Hawley argues it's only a war when "ground troops" are deployed. This rhetorical maneuvering highlights the political sensitivity surrounding what could become an unpopular military engagement.

Representative Tim Burchett's warning is more direct: "MAGA voters" should worry that Iran might become "another forever war." Such concerns reflect polling showing a majority of Americans disapprove of the Iranian strikes.

The Xi Jinping Calculation

These Republican dynamics could prove crucial in Trump's upcoming meeting with Xi. While Trump may prefer focusing on economic issues—seeking tangible achievements for Republican voters ahead of midterm elections—China likely sees broader opportunities.

From Beijing's perspective, this moment offers a chance to "look for cues" about how Trump might respond to other geopolitical flashpoints, particularly Taiwan. After all, this marks the second time in recent months that the U.S. has used military force against a country with close China ties.

What could embolden China is precisely the Republican unease about conflict duration. Given China's military capabilities and geographic proximity to Taiwan, any confrontation over the island could easily become a prolonged war of attrition—the ultimate concern for Republicans wary of long-term military entanglements.

The Domestic Constraint Factor

Many Republicans backing the administration may be doing so not from conviction, but because they believe the U.S. has "already crossed the Rubicon." They support seeing the conflict through to avoid undermining troops already engaged, but might have opposed initiating the war if given a prior vote.

This nuanced position creates a strategic vulnerability. If Republican support for the Iran conflict begins eroding—as history suggests it might—China may draw an important lesson: even a president with imperial tendencies like Trump struggles to sustain domestic political support for prolonged conflicts.
