Who’s in and who’s out of US foreign policy circles after Republicans lose the midterms

The Republican Party's significant defeats in the midterm elections are set to alter the course of US foreign policy. With control of key committees in the House and Senate, Democrats will gain the power to probe the Trump administration and influence legislation related to military spending, foreign aid, and international security.

In the House, Representative Gregory Meeks is set to become chairman of the foreign affairs committee, replacing Republican Brian Mast. Adjacent to this, Representative Adam Smith is expected to lead the House armed services committee, supplanting Republican Mike Rogers. These appointments signal a shift towards a more prominent Democratic presence in shaping foreign policy decisions.

The Senate is not exempt from change either. Jack Reed is expected to assume the role of chairman of the armed services committee, succeeding Republican Roger Wicker. Additionally, Chris Coons is predicted to take over the foreign relations committee following the retirement of Democratic leader Jeanne Shaheen in January.

The circumstances surrounding the Republican party's departures are varied. Senator Susan Collins' loss reflects her vital role as a senior voice on national security, yet Thom Tillis' retirement opens up a position previously held by the prominent bipartisan advocate for NATO and Ukraine support. Lindsey Graham's passing and the subsequent Democratic appointment as Senator have further reshaped the political landscape.

The absence of strong Republican national security experts in Congress has raised concerns among observers. Leslie Shedd, a non-resident fellow at the Atlantic Council’s Eurasia Centre, questions whether incoming politicians will maintain an internationalist approach or if the Republican Party will gravitate towards its isolationist wing.

The new Democratic chairmen of the foreign policy panels will play a pivotal role in determining the issues given congressional attention. The Iran war is anticipated to be a primary focus for Democrats, who have frequently challenged the Trump administration's decision to launch military operations without congressional authorization. Legislative priorities will also see the Democrats aiming to terminate President Trump's war with Iran and scrutinize the administration's budget and military priorities.

Changes in committee leadership could also impact US relations with Israel. The incoming Congress is expected to exert greater scrutiny on arms transfers and conditions attached to US support for the Israeli-Palestinian conflict. Furthermore, policy towards Ukraine is likely to be reassessed in light of Democrats' generally more supportive stance than under the Trump administration.

As the new Congress takes office in January, speculation persists about potential changes within the executive branch, particularly concerning the composition of President Trump's cabinet. While some murmurs have surfaced, no confirmations have been made. Secretary of State Marco Rubio is rumored to be considering a resignation, and Defence Secretary Pete Hegseth faces vulnerability due to the poorly received Iran war.

President Trump remains in the dark regarding any staffing changes, stating that the Pentagon chief had done a "fantastic job".
