Don't judge things on election narratives. People tells/Claims a lot during elections.
Maldives president won election purely on hate against India and Muzzi promised lots against India but in reality he is coming India next week to make relationship more better.
Barak Obama promised to close Abu Garib prison in Cuba in 2008 during election. He was elected twice but couldn't close the prison, infact ended up increasing the funding
Trump will do the same as Biden is doing today. Presidents change but foreign policy remain persistent.
If Ukraine lost the war then Trump will be blamed so he will be forced to continue the war.
