Last week Elbridge Colby, US President Donald Trump’s nominee for under secretary of defense for policy, a key advisory position, said in his Senate confirmation hearing that Taiwan defense spending should be 10 percent of GDP “at least something in that ballpark, really focused on their defense.” He added: “So we need to properly incentivize them.”
Much commentary focused on the 10 percent figure, and rightly so. Colby is not wrong in one respect — Taiwan does need to spend more. But the steady escalation in the proportion of GDP from 3 percent to 5 percent to 10 percent that advocates call for was predictable and inevitable. Set the bar high enough, and eventually Taiwan cannot reach it. And the US can wash its hands of it. Is that the plan?
WHAT INCENTIVES?

Colby’s remark that Taiwan needs to be “incentivized” to spend at least realizes that Washington can play a role in getting Taiwan to spend more. He also remarked that losing Taiwan would be a disaster for the US. Finally, he stated that he was “profoundly disturbed” by the pro-China parties — the Chinese Nationalist Party (KMT) and the Taiwan People’s Party (TPP) — slashing of defense budgets. Washington is aware of the problem. Hopefully the “incentives” Colby proposes will help address the problem of the China-aligned parties.
The stern moralizing of US-based commentators is in stark contrast to the reality of US military decline, a decline that has worsened palpably under Trump. Atlantic Council Fellow Elizabeth Braw explained this in Foreign Policy last week in a piece entitled “How Trump Is Killing the US Defense Industry.”
Braw observes that foreign leaders, seeing the way Trump treated Ukrainian President Volodymyr Zelenskiy, will conclude “that US security guarantees — a key reason why countries tend to buy US weapons—are not going to be a convincing argument anymore.”

The stock prices of US defense firms have slid 4 percent in the six weeks that Trump has been in power. Since European leaders now believe the US is no longer a reliable partner, their weapons purchases will shift to locally produced systems, Braw said. The stock prices of European defense firms have all risen as markets realize this.
Trump’s shocking, self-destructive reversal of longstanding American foreign policy has obscured the burgeoning impact of Elon Musk’s Department of Government Efficiency (DOGE) on US defense readiness. Last week Senator James Lankford of Oklahoma warned that DOGE wanted to slash jobs at the McAlester Army Ammunition plant in his home state.
“We can’t do ordinance if we remove 1000 civilians there,” Lankford said.
McAlester is a critical ammunition supplier. DOGE was also ripping away jobs at Tinker Air Force Base in Oklahoma, a key facility in US military aircraft maintenance. Colby has his work cut out for him, if his goal is to increase investment in the defense industrial base.
The ongoing demolition of the US alliance system and industrial base, combined with the negative effects of DOGE on government efficiency, bodes ill for the defense of Taiwan. It also makes it far more difficult to “incentivize” Taiwan to double or triple defense spending, since without US military intervention, Taiwan is doomed no matter how much it spends. Nor can defense spending by Taiwan (or the Philippines or Japan) deter the People’s Republic of China (PRC), despite widespread magical thinking among commentators in this regard. Only the threat of US intervention can do that.
NUMBERS DON’T ADD UP
But, assuming that the US will intervene if defense spending actually reaches that elusive, ever-receding goal that will please US policymakers, what goal is reasonable? Taiwan’s GDP last year reached US$793 billion, making 10 percent around $79 billion. The fiscal year budget last year was NT$2.85 trillion, or US$86 billion. That’s right, to reach 10 percent of GDP, Taiwan would have to convert its entire government budget to military spending, a fourfold increase in defense spending at fiscal year 2025 levels of US$19.7 billion (2.45 percent of GDP). Such a figure is absurd.
Even reaching 5 percent of GDP would require more than doubling the current defense budget. Are Taiwan’s relatively untaxed wealthy willing to pay more taxes for that?
Increases also imply other issues. In a recent piece at Global Taiwan Institute, Jeremy Chen (張智程) pointed out the growing problem of diminishing returns to military spending: growing costs for personnel, materials and maintenance costs squeeze procurement budgets. Doubling funding will thus not double performance. And still, US commentators will complain that it is not enough.
A better move for US-based pundits would be to stop demanding specific percentages or sums, all of which are unrealistic given Taiwan’s low tax take and the current legislature, controlled by the pro-PRC parties. Instead, the US can incentivize Taiwan to invest more in its defense over time by taking concrete actions that signal to all parties it remains strongly committed to the nation’s defense.
MEANINGFUL PROPOSALS
Many of these were in fact laid out in a bipartisan proposal containing 10 recommendations to deter the PRC by the House China Committee. Among other things, it called for pre-positioning munitions in Taiwan, joint training, a joint planning group, a joint headquarters group, hardening US Pacific bases, ramping up munitions production in the US and pre-planning for sanctions in coordination with US allies in Asia. These must be carried out.
What the US should also be doing is increasing its visible footprint in Taiwan. That will help it counter the steady flow of US skepticism served up by PRC propaganda. Having Major General Jay Bargeron of the US Indo-Pacific Command observe the recent Han Kuang military exercises last week was a good start (his identity should not have been downplayed). High ranking military officers should be regular and heavily publicized visitors. Familiarization trips by small groups of US military personnel who could be encountered across the island by the ordinary public would be even better.
In 2017, the US Senate Committee on Armed Services passed a provision that would permit US naval vessels to visit Kaohsiung or “other suitable ports.” The following year a US naval research vessel visited. It visited again last month, but both visits were low-key. Such visits need to become normalized and include a much greater range of vessels until warships can dock without much protest from the PRC. After all, Beijing will be bellicose whether or not the US does port visits.
Finally, the US should also begin a program of munitions procurement from Taiwan, which would enable it to expand its military production without increasing its military budget. US lawmakers and government officials also need to continue loudly scolding the China-aligned parties for their cuts to the proposed budgets. The US can also signal Taiwan by making its military relations with Japan more visible to Taiwan, and by rapidly expanding its military industrial base.
Simply demanding that Taiwan spend more, without major changes in US policy involving concrete cost signals of US commitment, will help the pro-China side argue that the US is useless, unreliable and venal. Indeed, this position has been made eminently reasonable by the US abandonment of Ukraine. Like it or not, US policymakers will have to shape their Taiwan policies to account for the effects of that historic betrayal.

April 28 to May 4 During the Japanese colonial era, a city’s “first” high school typically served Japanese students, while Taiwanese attended the “second” high school. Only in Taichung was this reversed. That’s because when Taichung First High School opened its doors on May 1, 1915 to serve Taiwanese students who were previously barred from secondary education, it was the only high school in town. Former principal Hideo Azukisawa threatened to quit when the government in 1922 attempted to transfer the “first” designation to a new local high school for Japanese students, leading to this unusual situation. Prior to the Taichung First
The Ministry of Education last month proposed a nationwide ban on mobile devices in schools, aiming to curb concerns over student phone addiction. Under the revised regulation, which will take effect in August, teachers and schools will be required to collect mobile devices — including phones, laptops and wearables devices — for safekeeping during school hours, unless they are being used for educational purposes. For Chang Fong-ching (張鳳琴), the ban will have a positive impact. “It’s a good move,” says the professor in the department of
On April 17, Chinese Nationalist Party (KMT) Chairman Eric Chu (朱立倫) launched a bold campaign to revive and revitalize the KMT base by calling for an impromptu rally at the Taipei prosecutor’s offices to protest recent arrests of KMT recall campaigners over allegations of forgery and fraud involving signatures of dead voters. The protest had no time to apply for permits and was illegal, but that played into the sense of opposition grievance at alleged weaponization of the judiciary by the Democratic Progressive Party (DPP) to “annihilate” the opposition parties. Blamed for faltering recall campaigns and faced with a KMT chair
Article 2 of the Additional Articles of the Constitution of the Republic of China (中華民國憲法增修條文) stipulates that upon a vote of no confidence in the premier, the president can dissolve the legislature within 10 days. If the legislature is dissolved, a new legislative election must be held within 60 days, and the legislators’ terms will then be reckoned from that election. Two weeks ago Taipei Mayor Chiang Wan-an (蔣萬安) of the Chinese Nationalist Party (KMT) proposed that the legislature hold a vote of no confidence in the premier and dare the president to dissolve the legislature. The legislature is currently controlled
