What security guarantees is Ukraine seeking in potential peace negotiations with Russia?

Ukraine is seeking strong security guarantees that include military presence to prevent future Russian invasions after any ceasefire agreement. As discussed during US envoy Keith Kellogg's visit with President Zelensky, Ukraine needs robust protection mechanisms to ensure its sovereignty remains intact following peace negotiations. However, Ukraine faces significant challenges as it attempts to insert itself into peace talks that are occurring without its full participation. The country is negotiating from a disadvantaged position as Russia appears to be achieving many of its strategic goals. Ukraine's leadership is concerned about maintaining sufficient international support to secure meaningful security guarantees that would prevent future aggression.
