If you consume all your resources and put yourself at a tactical and strategic risk for the next few turns while failing to achieve your objective that's essentially having your alpha strike being shrugged off. That can happen on both sides in the EA (and in other games too).
No...
Shrugging off an alpha strike means doing a full attack.
In this game's terms it would be using all your AP on attack.
In Mechwarrior/Battletech it was firing every gun you had.
Having tactical or strategic risk isn't necessary to the definition.
