China claims Taiwan as its own territory and has increased military pressure on the island in recent years through regular air and naval operations, prompting Taipei to accelerate efforts to modernize its military. The United States, while maintaining unofficial relations with Taiwan under the Taiwan Relations Act, remains the island’s largest arms supplier and has increasingly encouraged Taiwan to focus on “asymmetric warfare”—developing capabilities that can make a Chinese invasion costly rather than matching China’s military platform for platform.
The importance of drones has grown significantly following Russia’s invasion of Ukraine, where unmanned aerial and maritime systems have transformed modern warfare by providing reconnaissance, precision strikes and electronic warfare capabilities at relatively low cost. Taiwan has since made drone development a priority, although political disagreements over defence spending have slowed some procurement plans.
Why it matters
The remarks by the top U.S. diplomat signal that drones are becoming a cornerstone of Washington’s strategy for Taiwan’s defence. Rather than relying primarily on conventional fighter jets, tanks or warships, the United States increasingly believes large numbers of inexpensive drones can strengthen deterrence by making any military operation against Taiwan more difficult and costly.
The comments also reinforce deepening U.S.-Taiwan defence cooperation at a time when China has intensified military activities around the island. Any expansion of Taiwan’s drone capabilities is therefore likely to draw criticism from Beijing and add another point of tension in already strained U.S.-China relations.

Stakeholders
Taiwan: The government is seeking to rapidly expand domestic drone production and strengthen asymmetric defence capabilities while balancing political disagreements over defence budgets.
United States: Washington aims to help Taiwan improve its deterrence against China while promoting closer defence-industrial cooperation and reducing dependence on Chinese technology in critical sectors.
China: Beijing opposes all forms of U.S.-Taiwan military cooperation, viewing them as interference in its internal affairs and encouragement of what it considers separatist activities.
Taiwan’s opposition parties: While broadly supporting stronger drone capabilities, opposition lawmakers favour different funding mechanisms and spending priorities, which could influence how quickly programmes move forward.
Taiwan’s defence industry: Domestic companies stand to benefit from increased government investment as Taipei seeks to build a self-sufficient drone ecosystem.
Future outlook
Taiwan is expected to continue expanding investment in drones, unmanned surface vessels and other asymmetric weapons as it adapts to changing military threats. Whether those plans proceed at the pace envisioned by the government will depend on parliamentary approval of defence budgets and the capacity of local manufacturers to scale production.
The United States is also likely to deepen cooperation with Taiwan on drone technology, training and supply chains, reflecting a broader effort to strengthen the defence capabilities of democratic partners in the Indo-Pacific. Meanwhile, Beijing is expected to continue military pressure and diplomatic protests against closer U.S.-Taiwan security ties, ensuring that drones remain a central issue in cross-strait tensions.
Analysis
Greene’s “hornet’s nest” analogy reflects a significant shift in U.S. military thinking. For decades, Taiwan’s defence strategy focused largely on acquiring expensive conventional weapons such as fighter aircraft, tanks and naval vessels. Today, Washington increasingly believes Taiwan’s greatest advantage lies in asymmetric warfare using thousands of relatively inexpensive drones, missiles and unmanned naval systems to complicate any invasion attempt.
The strategy is heavily influenced by lessons from Ukraine, where drones have changed the nature of warfare by allowing smaller forces to inflict significant costs on a larger military. U.S. officials hope Taiwan can build similar capabilities that would raise the operational and financial costs of any Chinese military action.
However, developing such a deterrent will require more than technology. Taiwan must secure stable funding, expand domestic production, integrate drones into military planning and maintain political consensus on defence priorities. At the same time, deeper U.S.-Taiwan cooperation is likely to intensify strategic competition with China, making drone development not only a military issue but also a key element of the broader geopolitical rivalry in the Indo-Pacific.
