US President Donald Trump could face stronger congressional scrutiny over his foreign policy decisions after Democrats secured control of both chambers of Congress, according to experts cited by CNBC.
The shift could complicate funding for military operations in Iran and assistance to Ukraine. Democrats are expected to use congressional spending and oversight powers to challenge the administration’s approach to the Iran war.
Analysts believe the administration could face pressure to reconsider its military strategy as rising fuel and living costs affect voters. There are also concerns that Trump could push Ukraine towards a settlement favourable to Russia.
European officials have indicated that the continent may need to strengthen its support for Kyiv if US assistance weakens. However, experts warn that Europe cannot fully replace American military and intelligence capabilities.
