What are the concerns about Trump's approach to Russia-Ukraine negotiations?

Ukrainians are concerned that President Trump is approaching negotiations with Russia with a friendlier stance toward Russian interests than Ukrainian ones. Nancy Cordes highlights that Trump failed to acknowledge Russia's responsibility for creating the conflict, referring to it as 'barbarism' without mentioning that Russia initiated the hostilities. There are mounting worries that Trump might favor what Russians want from peace talks rather than supporting Ukraine's negotiation positions. This approach could potentially undermine Ukraine's leverage in any settlement discussions. These concerns are shared not only by Ukraine but also by US allies in Europe, and Trump's recent remarks did nothing to address or alleviate these apprehensions.
