House Homeland Security Committee Chairman Mark E. Green tells Threat Status that the committee is set to reveal new details of threats to the American homeland posed by China at a hearing Wednesday examining Beijing’s “information warfare” activities.

“The People’s Republic of China is working tirelessly to unseat the United States as the global hegemon, using the Chinese Communist Party as its greatest weapon of global information warfare,” the Tennessee Republican said.

The operations include Chinese infiltration of U.S. high education institutions, clandestine Chinese police stations in American cities, large-scale cyberespionage and subversion of critical U.S. supply chains, he said. Mr. Green said the activities demonstrate that Beijing is casting “an authoritarian shadow” on the United States and its allies.

Ahead of Mr. Zelenskyy’s arrival Friday, Mr. Trump is insisting that it is now or never to negotiate an end to the Russia-Ukraine war. Mr. Trump said at a joint press conference alongside British Prime Minister Keir Starmer on Thursday that a deal to end the war would “happen fairly quickly or not happen at all.”

Mr. Trump brushed aside pleas by Mr. Starmer not to reward Mr. Putin with a peace deal. French President Emmanuel Macron visited Washington earlier in the week with similar pleas.

Mr. Zelenskyy’s visit Friday is expected to produce a minerals deal that Mr. Trump contends will give the U.S. companies access to Ukrainian precious metals as “payback” for the tens of billions of dollars in military and development aid from Washington since Russia invaded in early 2022.

It remains to be seen whether the minerals deal will accelerate peace talks, with Russia and China watching developments closely.

While Mr. Trump has claimed the Ukrainian leader’s domestic political standing has cratered, his very public criticisms have ironically boosted Mr. Zelenskyy’s support at home, with many Ukrainians hoping Mr. Zelenskyy will stand firm as he meets the U.S. president at the White House on Friday.

Threat Status Special Correspondent Guillaume Ptak examines the situation in a dispatch from Kyiv, where foreign policy and security analyst James Rushton says ordinary Ukrainians struggle to understand the Trump administration’s shift from “peace through strength” to what they see as “appeasement through weakness,” amid Mr. Trump’s diplomatic outreach to Russia over the past month.

Some Ukrainian supporters in the Republican Party are speaking up on Mr. Zelenskyy’s behalf. “There seems to be moral ambiguity when it comes to the responsibility for starting this war. Russia started it, not Ukraine,” Rep. Don Bacon of Nebraska told Mr. Ptak in a telephone interview. “We stand on the side of what is right.”

Mr. Trump closed the U.S. Agency for International Development and ordered a review of all foreign aid programs to ensure they were consistent with his “America First” foreign policy. However, in today’s interconnected, competitive and strife-torn world, Mr. Trump “should take this opportunity to increase, not decrease, U.S. engagement with other countries through reformed aid to keep America safe and prosperous,” writes Steven R. Galster.

“An obscure part of U.S. foreign policy I have participated in for the past 25 years reveals the benefits to America far beyond its focus: combating global nature crime,” writes Mr. Galster the founder and chairman of Freeland, a U.S. nonprofit that works globally to counter the trafficking of wildlife and people. “For 11 years, I was a ‘chief of party’ of a USAID program in Asia that established government policies and networks to confront rampant poaching and trafficking.

“We and other U.S. grantees have been doing more than saving animals, trees and coral reefs in faraway lands,” he writes. “We’ve been helping governments (including the U.S.) locate, disrupt and dismantle transnational criminal rings that are raking in more than $20 billion a year on wildlife trafficking and more than $300 billion annually when we add illegal logging and fishing.”

The president has “suggested” that Egypt and Jordan provide temporary refuge to more than 1 million Palestinians, writes Washington Times Editor-at-Large David Keene, who notes that Mr. Trump “threatens foreign aid cutoffs and targeted tariffs if either country refuses, as both have vowed.”

“Since the current war began, as many as 150,000 Gaza Palestinians have legally and mostly illegally crossed the border into neighboring Egypt to join several hundred thousand others living and studying there,” writes Mr. Keene. “Many pay the Middle Eastern counterparts of the coyotes smuggling people over our southern border as much as $5,000 per person to get into Egypt despite that country’s efforts to choke off the migrant flood.

“Mr. Trump’s suggestion seems to make sense,” Mr. Keene writes. “Still, the nature of the refugees and the history countries of the region have had in dealing with Palestinian refugees make it unlikely that Egypt or Jordan will go along with him in the face of either threats or incentives.”
