Some possible triggers for NO:

• He resigns or otherwise loses the presidency before the war ends

• He dies before the war ends

• He is ousted from the presidency as a condition of the war ending (even if he is given a small transition period of less than a year)

• Russia ceases to exist as a nation

• He changes position or title to something other than "President"

Doesn't trigger a resolution:

• The war extends beyond Ukraine and is no longer considered the Ukraine-Russia war

• Ukraine ceases to exist as a nation, is annexed, or is renamed

• Russia is renamed

Otherwise, YES when the war ends. As per questions in the comments: for practical reasons, a formal armistice that is adhered to would qualify as the end of the war.

The close date on this market may be extended as needed.
