US Defence Secretary Pete Hegseth has reaffirmed the Trump administration’s defence commitments to America’s Pacific territories of Guam and Northern Mariana Islands and that any attack on them would be an attack on the mainland.
Hegseth touched down in Guam from Hawai’i on Thursday as part of an Indo-Pacific tour, his first as Defence Secretary, in which he is seeking to shore up traditional alliances to counter China.
Geostrategic competition between the US and China in the Pacific has seen Guam and neighboring CNMI become increasingly significant in supporting American naval and air operations, especially in the event of a conflict over Taiwan or in the South China Sea.
Both territories are also within range of Chinese and North Korean ballistic missiles and the US tested a defence system in Guam in December.
Any attack on Guam and the Commonwealth Northern Marianas Islands would be met with “appropriate response,” Hegseth said during his brief visit, emphasising both territories were central to the US defence posture focused on containing China.
“We’re defending our homeland,” Hegseth said. “Guam and CNMI are vital parts of America, and I want to be very clear — to everyone in this room, to the cameras — any attack against these islands is an attack against the US.”
“We’re going to continue to stay committed to our presence here,” Hegseth said. “It’s important to emphasise: we are not seeking war with Communist China. But it is our job to ensure that we are ready.”
Key US strategic asset
Located closer to Beijing than Hawai’i, Guam serves as a key US strategic asset, known as the “tip of the spear,” with 10,000 military personnel, an air base for F-35 fighters and B-2 bombers, and home port for Virginia-class nuclear submarines.
The pledge from Hegseth comes as debate on Guam’s future as a US territory has intensified, with competing calls by some residents for full statehood and UN-mandated decolonisation, led by the Indigenous Chamorro people.

Defending Guam and CNMI, Hegseth said, aligns with President Donald Trump’s “goal to achieve peace through strength by putting America first”.
He delivered remarks at Andersen Air Force Base and took an aerial tour of the island before meeting with Lou Leon Guerrero and Arnold Palacios, governors of Guam and Northern Marianas, respectively.
Guerrero appealed to Hegseth about the “great impact” the US military buildup on Guam had had on the island’s residents.
“We welcome you, and we welcome the position and the posture that President Trump has,” Guerrero told Hegseth, during opening statements before their closed-door meeting.
“We are the centre of gravity here. We are the second island chain of defence,” she said. “We want to be a partner in the readiness effort but national security cannot happen without human health security.”
Funding for hospital
Guerrero sought funding for a new hospital, estimated to cost US$600 million.
“Our island needs a regional hospital capable of handling mass casualties — whether from conflict or natural disasters,” she told Hegseth.
“We are working very closely in partnership with the military, and one of our asks is to be a partner in the financing of that hospital.”
Afterwards Guerrero told reporters she did not have time to discuss the housing crisis caused by the US military buildup.
Earlier this month, Guerrero warned in her “state of the island” address of US neglect of Guam’s 160,000 residents, where one-in-five are estimated to live below the poverty line.
“Let us be clear about this: Guam cannot be the linchpin of American security in the Asian-Pacific if nearly 14,000 of our residents are without shelter, because housing aid to Guam is cut, or if 36,000 of our people lose access to Medicaid and Medicare coverage keeping them healthy, alive and out of poverty,” Guerrero said.
At the end of his visit to Guam, Hegseth announced in a statement he had also reached an “understanding” with President Wesley Simina of the Federated States of Micronesia to begin planning and construction of US$400 million in military infrastructure projects in the State of Yap.
Territorial background
Simina’s office would not confirm to BenarNews he had met with Hegseth in Guam, saying only he was “off island.”
As a territory, Guam residents are American citizens but they cannot vote for the US president and their lone delegate to the Congress has no voting power.
The US acquired Guam in 1898 after winning the Spanish-American War, and CNMI from Japan in 1945 after its defeat in the Second World War. Both remain unincorporated territories to this day.
The Defence Department holds about 25 percent of Guam’s land and is preparing to spend billions to upgrade the island’s military infrastructure as another 5000 American marines relocate from Japan’s Okinawa islands.
On Tuesday, Hegseth was in Hawai’i meeting officials of the US Indo-Pacific Command. Speaking with the media in Honolulu, he said his Asia-Pacific visit was to show strength to allies and “reestablish deterrence.”
Hegseth’s week-long tour comes against a backdrop of growing Chinese assertiveness. Its coast guard vessels have recently encroached into the Philippines’ exclusive economic zone in the South China Sea and around the Japanese-controlled Senkaku Islands in the East China Sea.
His visit will be closely watched in the Pacific for signs of the Trump administration’s commitment to traditional allies following a rift between Washington and Europe that has tested the transatlantic alliance.
The trip also threatens to be overshadowed by the fallout from revelations that he and other national security officials discussed attack plans against Yemen’s Houthis on the messaging app Signal with a journalist present.
Flagrant violation
Critics are calling it a flagrant violation of information security protocols.
During his first term, Trump revived Washington’s engagements in the Pacific island region after long years of neglect paved the way for China’s initiatives.
He hosted leaders of the US freely associated states of Palau, Marshall Islands and Federated States of Micronesia at the White House in 2019.
The Biden administration followed through, doubling the engagement with an increased presence and complementing the military buildup with economic assistance that sought to outdo China’s Belt and Road Initiative.
The new Trump administration, however, cut the cord, dismantling the US Agency for International Development (USAID), and along with it, the millions of dollars pledged to Pacific island nations.
The abolition of about 80 percent of USAID programmes sent mixed signals to the island nations and security experts have warned that China would fill the void it has created.
From Guam, Hegseth has travelled to Philippines and Japan, where he will participate in a ceremony commemorating the 80th anniversary of the Battle of Iwo Jima and will later meet with Japanese leaders and US military forces.
