Q. USA plays Grain Sales and sees the USSR Headline. Grain Sales resolves first. When the USA draws a card from the USSR Hand it turns out to be Defectors. Can it be played immediately to cancel the USSR Headline?
A: If the US player's event resolved BEFORE the USSR headline, then the text of Grain Sales would allow him to play Defectors immediately and cancel the USSR headline event. If the USSR's event was already resolved then Defectors could not cancel it because it has already occurred. You cannot cancel an event AFTER it resolves because the US doesn’t have a time machine…yet!
因为苏联的肃反事件已经清算，美国不能回头去取消它了，除非时光倒流
