What concerns are raised about a potential Trump-Russia deal regarding European security interests?

The primary concern is that a swift deal between Trump and Russia could potentially overlook European security interests while rewarding Russia. Such an arrangement might allow Putin to maintain his ability to threaten Ukraine and possibly other countries in the future, effectively undermining regional stability. The absence of Ukraine and European leaders from the Riyadh talks has raised significant doubts about their influence in negotiations that directly impact their security. This situation creates a troubling scenario where decisions affecting European security could be made without adequate representation from the stakeholders most affected by these outcomes.
