President Donald Trump's decision to halt shipments of US military aid to Ukraine has raised concerns among analysts at the UK-based Royal United Services Institute (RUSI) think tank. According to RUSI's deputy director general, Malcolm Chalmers, this move could potentially embolden Russian President Vladimir Putin to demand further concessions.
Chalmers emphasized that Trump's decision appears to be driven by a belief that Russia may be open to a peace deal, with Ukraine being the perceived obstacle. However, there is a lack of evidence to support this assumption, leaving the potential terms of any such deal uncertain.
Chalmers warned that Putin might leverage this situation to push for additional demands, such as Ukrainian demilitarization and neutrality. He expressed concerns that a US-Russia agreement could be reached swiftly, leaving Ukraine and Europe with limited options.

While only about 20% of Ukraine's military hardware is supplied by the United States, Chalmers noted that this portion includes some of the most critical and potent weaponry. Despite Ukraine's ability to withstand aid cutoffs, the cumulative impact of such actions could still be significant.
Chalmers also highlighted the role of European support in reassuring Ukraine, particularly through offers of military assistance. However, he underscored the importance of the UK and Europe's willingness to stand by Ukraine in the face of shifting geopolitical dynamics.
Overall, the decision to pause military aid to Ukraine has sparked concerns about the potential implications for regional stability and the balance of power in Eastern Europe. Analysts continue to monitor the situation closely as diplomatic negotiations unfold.
