The House Armed Services Committee will convene on March 18, 2026, to examine U.S. military posture Europe strategy and the national security challenges confronting American forces across the continent. The hearing — titled "U.S. Military Posture and National Security Challenges in Europe" — comes as Congress grapples with evolving threats, alliance tensions, and questions about the scale and purpose of American military commitments on NATO's eastern flank.
Two senior defense officials will testify: Daniel Zimmerman from the Office of the Secretary of Defense and Alexus Grynkewich from U.S. European Command. This is an oversight session designed to take the temperature of American defense strategy before the committee begins shaping the next National Defense Authorization Act.
Why This Hearing Is Happening Now
Geopolitical Pressure and Alliance Friction
The hearing arrives against a backdrop of sustained geopolitical tension in Europe. Committee members from both parties have been vocal about the state of European defense posture and the U.S. role in maintaining it — though they disagree sharply on what that role should look like.
Rep. Joe Wilson (R-SC-2) has warned that "War Criminal Putin has committed nearly 150 known acts of terrorism or sabotage on NATO territory" since the start of the Russia-Ukraine conflict, framing the threat environment as one that demands continued American engagement. Wilson also attended the Munich Security Conference, where he said he looked forward to "promoting PEACE THROUGH STRENGTH & talking to world" leaders.
On the Democratic side, Rep. Chrissy Houlahan (D-PA-6) expressed "disappointment with Vice President Vance's speech at the Munich Security Conference," pointing to friction within the administration's own approach to European allies. Rep. Bill Keating (D-MA-9) was more pointed, saying "JD Vance is lecturing our European allies on democracy while ignoring court orders & risking a constitutional crisis."
Keating also highlighted direct engagement with Baltic allies, noting discussions on "the importance of NATO with our Baltic friends: Latvian Foreign Minister, Estonian Foreign Minister."
These exchanges suggest the hearing will feature pointed questions about whether the administration's diplomatic posture is aligned with its military posture — and whether U.S. military Europe commitments are being undermined by political signals from Washington.
Defense Readiness Concerns
Several Republican members have zeroed in on military readiness as a core concern heading into the hearing.
Rep. Pat Fallon (R-TX-4) argued that "under Biden, U.S. defense spending as a percentage of GDP hit historic lows — lower than before WWII," and separately warned that the U.S. has "grown complacent in getting new technology to our troops." Fallon also praised an executive order "to prioritize military excellence and readiness" and stated that "our military must be prepared to confront the threats and challenges of the coming decade."
Committee Vice Chair Rep. Rob Wittman (R-VA-1) framed the issue through the lens of military families, arguing that "standing by our military families isn't just the right thing to do — it's patriotic and supports our national security."
Rep. Jason Crow (D-CO-6) offered a different angle, saying Congress can "save taxpayer dollars, make government more efficient, and better protect America's national security by reforming" defense processes.
Meanwhile, Rep. Joe Courtney (D-CT-2) joined Ranking Member Rep. Adam Smith in pressing the administration over a stop-work order affecting U.S. defense programs — a move that could directly bear on NATO military readiness and European defense posture.
Who's Spending on U.S. Military Europe and NATO Issues
While the hearing has no legislation on the docket, the lobbying ecosystem around its subject matter is active and well-funded. Over the last four quarters — from the Third Quarter of 2024 through the Second Quarter of 2025 — more than 15 organizations filed lobbying disclosures on topics directly tied to the hearing's focus on national security challenges Europe presents.
Lockheed Martin Corp. stands out as the largest spender, reporting approximately $3.89 million per quarter in the First and Second Quarters of 2025 on defense lobbying that included European military topics. The company filed multiple disclosures across the period.
Baltic and Eastern European advocacy groups have maintained a steady lobbying presence. The Baltic American Freedom League reported $10,000 in both the Third and Fourth Quarters of 2024, focused on NATO and Baltic security. The Joint Baltic American National Committee filed in all four quarters on NATO alliance security and defense cooperation.
Ukraine-related lobbying has also been consistent. Razom Inc., a Ukrainian-American advocacy organization, reported $20,000 in the Third Quarter of 2024 for Ukraine defense aid lobbying. The National Association of Ukrainian Defense Industries (NAUDI) filed in the Second Quarter of 2025 on Ukrainian defense industry cooperation.
Other notable filers include Deterrence Defense Inc., the International Stability Operations Association, and defense training firm CAE USA Inc. — all of which filed on topics touching European military readiness and defense posture.
PAC Money Flowing to Committee Members
The political spending picture reinforces the lobbying footprint. Lockheed Martin's employee PAC alone has made 4,869 contributions to campaign committees on record, with typical donations ranging from $1,000 to $5,000. CAE USA's PAC made 48 contributions, including $2,000 to House Armed Services Committee Chair Rep. Mike Rogers.
The broader defense contractor PAC universe is substantial. Boeing's PAC has 3,934 contribution records, General Dynamics has 3,081, Raytheon Technologies has 2,266, Northrop Grumman has 2,216, BAE Systems has 1,497, and L3Harris has 1,456. Frequent recipients across these PACs include members who sit on defense-related committees.
What to Watch at the Hearing
Based on member communications, expect the House Armed Services Committee hearing to break along several fault lines:
Russia and Ukraine: Rep. Wilson will likely press witnesses on the direct threat Russia poses to NATO territory and the implications of the Ukraine conflict for U.S. European Command operations. Democrats like Rep. Keating and Rep. Houlahan may push on whether administration rhetoric toward allies is undermining deterrence.
Defense spending and readiness: Rep. Fallon and other Republicans are expected to argue that spending levels are insufficient for the threat environment. Witnesses from the Office of the Secretary of Defense and EUCOM will face questions about whether current force levels and capabilities match the security demands.
Alliance management: The Munich Security Conference fallout — visible in communications from members on both sides — suggests that the diplomatic dimension of U.S. military Europe strategy will get significant attention. Members may ask whether military posture can compensate for political uncertainty in the alliance.
Defense reform and efficiency: Democrats like Rep. Crow may use the hearing to argue that better outcomes are possible through reform rather than simply increased spending.
The Bottom Line
This hearing is a pressure test. The committee wants to understand whether U.S. military posture in Europe matches the threat environment — and whether the administration's diplomatic approach is helping or hurting. With senior EUCOM and Pentagon officials in the witness chairs, and a committee divided on the right approach to European defense posture, the March 18 session will set the terms of debate for the defense authorization fight ahead.
The defense industry is watching closely, the advocacy community is engaged, and committee members have already staked out their positions. What remains to be seen is whether the testimony produces consensus — or deepens the divide over America's role in European security.
