One of the potentially interesting and controversial aspects that emerged during the Republican candidates' debate concerns the conflict in Ukraine, WP reports.


Donald Trump and several other presidential contenders are in favor of reducing the pace of support for Ukraine and an immediate ceasefire.


At the same time, their opponents, including former Vice President Mike Pence, believe that Joe Biden's administration should do more to support Kyiv.


The situation has uncertain implications for Europe, as whichever candidate is likely to win the Republican primary, if elected president, could suddenly change the US commitment to Ukraine and European defense.
