I'd imagine the same. Big gatherings and memorials and lots of coverage on the news and the equivalent of social media in The Grid.70 years today since the St Patrick's Day Raid on 17th March 1954.
I imagine that there is memorials in New York and Washington DC to those who were killed.
It would be seen as the turning point just like the Japanese attack on Pearl Harbor which in this ATL still happens the same way and date as OTL.
