Quagmire* says the following:
On next action round, US player must discard an Operations card worth 2 or more and roll 1-4 to cancel this event. Repeat each US player Action round until successful or no appropriate cards remain. If out of appropriate cards the US player may only play scoring cards until the next turn.
I know this can be used on AR 6 to discard an undesirable card with sufficient Ops on turn 7. But what happens if you play it on turn 7?
It says "on next action round" at the beginning. Does that mean AR 1 on the next turn? Or does it go away at the end of the turn?
