MUNICH, GERMANY: Sen Mark Kelly departed the Munich Security Conference on Sunday, February 15, with a sharp critique of President Donald Trump’s actions and their impact on the North Atlantic Treaty Organization (NATO).

In a statement posted on the social platform X, Kelly asserted that Trump had fundamentally weakened the alliance with European partners. His remarks reflected growing concern among US lawmakers about the administration’s foreign policy direction and its effects on global security.

As the conference drew to a close, Kelly used his departure to lambast Trump for what he described as significant damage to NATO and broader security alliances, "It took a World War and eight decades to build the strongest alliance that this world had ever seen. It took less than a year to practically destroy it."

Kelly wrote on X that “it took the president less than a year to practically destroy the NATO alliance,” arguing that both Russia and China are now benefiting from Trump’s confrontational posture toward European allies.

Kelly highlighted the "loss of trust" between the US and its traditional partners, asserting that Trump’s behavior has made it clear to European leaders that the American commitment to collective defense may no longer be reliable.

He further said that this lack of trust was “obvious” during his own meetings with numerous presidents, prime ministers, and defense and foreign ministers at the conference.

In his critique, the senator contrasted his views with those expressed by Secretary of State Marco Rubio at the conference. Rubio extended a message of unity with Europe but also criticized its embrace of mass migration and green energy policies.

Kelly specifically pointed to Trump’s threats to seize Greenland from Denmark as a notable example of actions that have damaged Washington’s image abroad. According to Kelly, such behavior drives European countries to seek alternative partners for trade and security cooperation, a shift he warns “makes you poorer and less safe.”

Mark Kelly cautions on Ukraine and China's rise

Beyond criticizing Trump’s approach to NATO, Kelly expanded his argument to broader global strategic concerns, focusing heavily on China’s rise and the conflict in Ukraine.

He said, "It will be incredibly hard to build what comes next, but we have to figure out a better path forward. Make no mistake, China is rising. Our ability to keep up with them and prevent a conflict depends on trusted, reliable alliances."

Kelly further emphasized, "So does ending the war in Ukraine in a way that keeps Putin from moving on to his next target. And so does growing our economy and protecting American workers in the age of AI."

Concluding his remarks, Kelly pointed to reactions from around the world as the conference ended. While delegates celebrated the close of the Munich event, he warned that “the champagne corks were popping in Beijing and Moscow.”

Kelly is also involved in an ongoing legal dispute with the Pentagon stemming from a video he recorded last fall alongside other Democratic lawmakers with military and intelligence experience. In the video, they encouraged service members to refuse unlawful orders.

Earlier this week, a federal judge issued a ruling preventing Defense Secretary Pete Hegseth from formally reprimanding Kelly or reducing his retirement rank over his participation in the recording.
