после драки кулаками не машут

• ПОСЛЕ ДРАКИ КУЛАКАМИ НЕ МАШУТ{{}}

[saying]

=====

⇒ it is senseless to show one's indignation about, or try to take measures concerning, a matter that has already been completed (said when one tries to rectify a matter or situation when it is too late):

- - why throw punches when the fight is over;

- you don't shake your fist when the fight is over;

- there's no use locking the barn door after the horse is gone (stolen);

- it is easy to be wise (bold) after the event.

     ♦ ...Если уж быть до конца честным, надо признаться, что, будь моя статья об этой декаде более яркой, хотя бы в лучших её местах, думаю, не пожалели бы на меня медали. Но, как говорится, после драки кулаками не машут (Искандер 4). ...То be perfectly honest, I think the truth is that they would have coughed up a medal for me, if my write-up on the festival-even just the key passages - had been more brilliant. But, as the saying goes, you don't shake your fist when the fight is over (4a).
