Mike Waltz, a former Army Green Beret and current Republican congressman from Florida, has been a vocal critic of China’s influence and a firm advocate for strengthening U.S. defense. Known for his unyielding stance on national security, Waltz is a long-time ally of Donald Trump and has backed the former president’s approach to foreign policy. With his recent appointment as Trump’s National Security Adviser, Waltz is positioned to play a major role in shaping U.S. national security policy.

Why did Trump select Waltz for this role?

Donald Trump’s decision to pick Waltz for the National Security Adviser role reflects a commitment to a hardline approach on China and broader national security issues. Trump and Waltz share a similar vision on foreign policy, especially regarding what they see as an aggressive stance needed to counter China. This appointment signals that Trump may intend to take a stronger stance on global defense, specifically focusing on China’s influence in the Indo-Pacific region.

Waltz’s view on China and national security

One of the main reasons for Waltz’s appointment is his outspoken criticism of China. Waltz has called for strengthening U.S. alliances in the Asia-Pacific and has repeatedly warned of the risks posed by China’s growing military and economic influence. In his recent book, Hard Truths: Think and Lead Like a Green Beret, Waltz outlined a strategy to deter China, which includes:

  • Providing military support to allies like Taiwan
  • Reinforcing U.S. military presence in the Asia-Pacific
  • Modernizing U.S. defense capabilities

Waltz believes that U.S. preparedness in the Indo-Pacific is crucial to maintain a balance of power and prevent potential conflict.

What does this mean for the U.S. military?

Waltz has a reputation for being critical of the Pentagon’s current policies. He advocates for a culture of accountability within the military and has raised concerns over what he views as “political” policies. Recently, he introduced legislation aimed at eliminating what he considers unnecessary diversity, equity, and inclusion (DEI) programs in the military, emphasizing the need for a return to “merit-based” evaluations.

By taking on this advisory role, Waltz could push for reforms in military practices and structure. He has also openly stated that the Pentagon needs leaders who are willing to make tough decisions and prioritize efficiency over bureaucracy.

Will Waltz’s foreign policy views impact relations with allies?

While Waltz has voiced support for America’s alliances, he also emphasizes the importance of direct and sometimes tough conversations. He has praised Trump’s past efforts to press NATO allies to increase defense spending, showing his belief in shared responsibility. This approach suggests that Waltz, as National Security Adviser, might encourage allied nations to take a more active role in global security.

What are Waltz’s views on Ukraine?

While initially supportive of military aid to Ukraine following Russia’s 2022 invasion, Waltz has since raised questions about U.S. objectives in the region. He has expressed concern that continued support for Ukraine might divert critical resources away from preparing for potential threats in the Asia-Pacific. His stance indicates that, while he values aiding Ukraine, he believes U.S. strategy should remain focused on long-term security concerns related to China.

Waltz’s loyalty to Trump and conservative values

Waltz has remained a firm supporter of Trump and even showed up in a court hearing in support of the latter earlier this year. His traditional views on military culture and emphasis on the defense of the United States are in sync with Trump. This relationship indicates that, amongst others, Waltz is likely to strengthen Trump’s foreign policy particularly on China.

The appointment of Mike Waltz is a move towards a more hawkish foreign policy, particularly with regard to China, and underlines Trump’s intention to transform the American military doctrine in the years to come.

Why did President Trump remove Waltz from his role as National Security Advisor?

In March 2025, Waltz inadvertently added journalist Jeffrey Goldberg to a Signal group chat where classified military plans concerning a U.S. strike on Houthi militants in Yemen were being discussed. This incident, dubbed “Signalgate,” led to widespread criticism and concerns over the handling of sensitive information .

As a result, on May 1, 2025, President Trump dismissed Waltz from his role as National Security Advisor. Despite the dismissal, Trump announced his intention to nominate Waltz as the U.S. Ambassador to the United Nations, a position that requires Senate confirmation 

The “Signalgate” scandal not only led to Waltz’s removal but also highlighted ongoing issues within the Trump administration regarding the use of non-secure communication platforms for sensitive discussions
