France fought for years trying to keep Algeria; they couldn’t hold onto it because only 10% of the population was French. We did the same with the Philippines, Portugal did it in Angola - their positions were untenable.
(FWIW: I’m not defending De Gaulle)
“..We did the same with the Philippines”
An rather inexact comparison with those other examples, I must say.
