Washington, Dec 19 (AP) US Secretary of State Marco Rubio weighed in on Russia-Ukraine and Israel-Hamas peace efforts and defended the Trump administration's increasing military pressure on Venezuela during a rare, end-of-year news conference Friday.

In a freewheeling meeting with reporters running more than two hours, Rubio also defended President Donald Trump's radical overhaul in foreign assistance and detailed the administration's work to reach a humanitarian ceasefire in Sudan in time for the new year.

Rubio's appearance in the State Department briefing room comes as key meetings on Gaza and Russia-Ukraine are set to be held in Miami on Friday and Saturday after a tumultuous year in US foreign policy.

Rubio has assumed the additional role of national security adviser and emerged as a staunch defender of Trump's “America First” priorities on issues ranging from visa restrictions to a shakeup of the State Department bureaucracy.

The news conference is taking place just hours before Trump's special envoy Steve Witkoff meets with senior officials from Egypt, Turkey and Qatar to discuss the next phase of the Republican president's Gaza ceasefire plan, progress on which has moved slowly since it was announced in October.

Witkoff and other US officials, including Trump son-in-law and informal adviser Jared Kushner, have been pushing to get the Gaza plan implemented by setting up a “Board of Peace” that will oversee the territory after two years of war and create an international stabilisation force that would police the area.

On Saturday, Witkoff, Kushner and Rubio, who will be at his home in Florida for the holidays, are to meet with Russian President Vladimir Putin's adviser Kirill Dmitriev in Miami to go over the latest iteration of a US-proposed plan to end the Russia-Ukraine war.

Rubio said there would be no peace deal unless both Ukraine and Russia can agree to the terms, making it impossible for the US to force a deal on anyone. Instead, the US is trying to "figure out if we can nudge both sides to a common place”.

“We understand that you're not going to have a deal unless both sides have to give, and both sides have to get," Rubio said. "Both sides will have to make concessions if you're going to have a deal. You may not have a deal. We may not have a deal. It's unfortunate." The US proposal has been through numerous versions with Trump seesawing back and forth between offering support and encouragement for Ukraine and then seemingly sympathising with Putin's hard-line stances by pushing Ukrainian President Volodymyr Zelenskyy to agree to territorial concessions.

Kyiv has rejected that concession in return for security guarantees intended to protect Ukraine from future Russian incursions.

On Venezuela, Rubio has been a leading proponent of military operations against suspected drug-running vessels that have been targeted by the Pentagon in the Caribbean Sea and the eastern Pacific Ocean since early September.

The Trump administration's actions have ramped up pressure on leftist Venezuelan President Nicolás Maduro, who has been charged with narco-terrorism in the US.

In an interview with NBC News on Friday, Trump would not rule out a war with Venezuela. But Rubio and Defence Secretary Pete Hegseth have publicly maintained that the current operations are directed at “narco-terrorists” trying to smuggle deadly drugs into the United States.

Maduro has insisted the real purpose of the US military operations is to force him from office.

Rubio sidestepped a direct question about whether the US wants “regime change in 2026” in the South American country.

“We have a regime that's illegitimate, that cooperates with Iran, that cooperates with Hezbollah, that cooperates with narco-trafficking and narco-terrorist organisations,” Rubio said, “including not just protecting their shipments and allowing them to operate with impunity, but also allows some of them to control territory.” Rubio defended Trump's prerogatives on Venezuela and said the administration believes “nothing has happened that requires us to notify Congress or get congressional approval or cross the threshold into war.” He added, “We have very strong legal opinions.” Trump has spoken of wanting to be remembered as a “peacemaker,” but ceasefires his administration helped craft are already in trouble due to renewed military action between Cambodia and Thailand in Asia and Rwanda and the Democratic Republic of the Congo in Africa.

Rubio, however, said those deals helped create a list of commitments that can now be used to bring both sides back to peace.

“Those commitments today are not being kept,” Rubio said of the Thailand-Cambodia conflict, which now threatens to reignite following Thai airstrikes. ”The work now is to bring them back to the table." Rubio's news conference comes just two days after the Trump administration announced a massive $11 billion package of arms sales to Taiwan, a move that infuriated Beijing, which has vowed to retake the island by force if necessary.

Trump has veered between conciliatory and aggressive messages to China since returning to the Oval Office in January, hitting Chinese imports with major tariffs but at the same time offering to ease commercial pressure on Beijing in conversations with China's President Xi Jinping.

The Trump administration, though, has consistently decried China's increasingly aggressive posture toward Taiwan and its smaller neighbours in disputes over the South China Sea.

Since taking over the State Department, Rubio has moved swiftly to implement Trump's “America First” agenda, helping dismantle the US Agency for International Development and reducing the size of the diplomatic corps through a significant reorganisation.

Previous administrations have distributed billions of dollars in foreign assistance over the past five decades through USAID.

Critics have said the decision to eliminate USAID and slash foreign aid spending has cost lives overseas, although Rubio and others have denied this, pointing to ongoing disaster relief operations in the Philippines, the Caribbean and elsewhere, along with new global health compacts being signed with countries that previously had programs run by USAID.

“We have a limited amount of money that can be dedicated to foreign aid and humanitarian assistance," Rubio said. “And that has to be applied in a way that furthers our national interest.” (AP) SCY SCY
