If French strategy in 1953-1954 doesn't veer into expanding their operations into the Laotian highlands and thus Paris avoids Dien Bien Phu, the political will to keep Algeria, which was won militarily by 1962, will likely be there. As a permanent UN Security Council member, they also retain the ability to prevent any sanctions for doing so. Outside of that, the Dutch keeping their portion of New Guinea as well as Suriname is also likely, as is Malta for the UK as noted previously in all three cases.
