They’re all dead Jim.
Go to the cemetery on Memorial day and see how many stones are now undecorated. Even the people who remember them are dying.
Children of some considerable age don’t even know what D-day is let alone anything about it or remembrances.
Just as with the D-Day battle other notables over the years like
Chosin Reservoir, Korea
TET 68, South Vietnam
Battle for Fallujah, Iraq
Are all destined for the memory hole and only vividly remembered by the aged and aging Veteran population that actually fought in them.
