President-elect Donald Trump has appointed Florida Congressman Mike Waltz as his National Security Adviser. Waltz, a retired Army National Guard Colonel and former Green Beret, has served multiple combat tours and has a strong background in defense policy, having worked in the Pentagon under former Defense Secretaries Donald Rumsfeld and Robert Gates. Known for his hawkish stance on China and advocacy for a stronger US-India alliance, Waltz has been a vocal critic of the Biden administration's withdrawal from Afghanistan. His appointment comes amidst concerns on Capitol Hill about pulling GOP members from the House, which could trigger new elections. Waltz will play a crucial role in addressing various national security challenges, including tensions in Ukraine and the Middle East, as well as US-China relations. The appointment is significant as it does not require Senate confirmation, allowing Trump to swiftly fill key positions in his incoming administration.
