Noel Gallagher apparently wanted to show the people the terrorists didn't win, because he bravely vacationed in Italy with his wife.
You'll recall ... Noel was MIA at Ariana Grande's One Love Manchester concert ... much to the dismay of his brother.
Liam Gallagher blasted his brother Monday for skipping out on the Sunday's benefit concert ... saying "Manchester id like to apologise for my brothers absence last night very disappointed stay beautiful stay safe LG."
He went on to say ... "Noels out of the f**king country weren't we all love get on a f**king plane and play your tunes for the kids you sad f**k."
The pair has been like Cain and Abel since Oasis' split in '09.
