Before meeting with Trump on Sunday, Zelensky stated that Ukraine has its own "red lines" regarding a peace agreement, but Trump is confident he can find a compromise. If Ukraine's red line is the territorial issue, it is estimated that this round of Russia-Ukraine talks will still not be optimistic, as there are clear contradictions between Russia and Ukraine regarding territorial issues. Personally, I don't think Trump can find an effective compromise unless Ukraine's red line is not about territorial issues!
