Robert O’Brien, who served as former President Donald Trump’s national security adviser, laid out his vision of what the U.S. needs to do to prevent a war from breaking out with China in the next several years.

O’Brien made the remarks during a Sunday interview with Margaret Brennan on CBS News’ “Face The Nation” when asked what another Trump administration would do if China invaded Taiwan.

“It’s called strategic ambiguity,” O’Brien said. “And we don’t tell the Chinese how we’re going to react to their actions. But the key thing is peace through strength. If we have a strong Navy, if we move our soldiers and Marines out of Europe, in Germany, where they’re garrisoned, and put them in Guam and Hawaii and the Philippines, and Australia, where we have Marines already, that sends a strong message to the Chinese not to invade.”

“The key is to deter war, not to fight and win a war, which we need to do if it happens,” he continued. “But we need to deter the Chinese and the Communist Party from – from invading Taiwan in the first place, which we failed to do with Russia in Ukraine. And so strength will deter the Chinese from invading. it’s not talk. It’s how they see our force posture.”

He said that the Marines were perfectly suited to fight in Asia and that they would be a greater deterrent there than in Europe where war has already broken out.

O’Brien said that the U.S. also needed to move a carrier strike group to the region to again send China a message to not invade.

“We need to increase our energy production,” he said, adding that the U.S. also needed to “rebuild our military, rebuild our Navy, get our shipyards producing ships again.”

Sen. Elizabeth Warren (D-MA) said over the weekend that Democrats want a “pathway to citizenship” for the millions of illegal aliens that have entered the U.S.

Warren made the remarks during a Sunday ABC News interview on “This Week” with Martha Raddatz when pushed about President Joe Biden’s failure on immigration and border security.

“We need a pathway to citizenship for people who are here, for spouses, for dreamers, for essential workers, for people who serve in our military, for people who come to school here and want to help make this a stronger country,” she said.

Warren blamed Republicans for the crisis that Biden unleashed on the U.S. southern border when he came into office and reversed all of former President Donald Trump’s border policies.

Raddatz compared the number of illegal aliens that have entered the U.S. under Biden, which some estimates say is north of 10 million, to the 2 million who entered during Trump’s first term in office.

“What did the president do wrong?” Raddatz asked.

“No, this isn’t about what the president did wrong,” Warren claimed. “Remember, on the very first day that he was sworn into office, President Biden asked Congress both for the resources and for comprehensive immigration reform. The Republicans blocked it, blocked it, blocked it, blocked it.”

Raddatz fired back: “Donald Trump didn’t have that either, Senator. He didn’t have that either, and there were 2 million during his entire term.”

Raddatz also noted that voters overwhelmingly trust Trump more than Biden when it comes to immigration and securing the border.
