The UK's Strategic Defence Review (SDR) is a ten year plan for how to defend itself, and the most recent envisages a proportionate allocation of funding divided among re-usable drones, kiss-goodbye drones and crewed platforms at a ratio of some 40, 40 and 20 percent... although the government has yet to commit to funding it to an extent it appears to require.
Of more concern to the more military-minded is apparently the fact the PM's urgent admonition that defence will involve all of us... appears to have fallen on deaf ears, and the chances are he's forgotten he ever said it himself.
It does though follow the great British tradition of never being ready: we even had a king called 'Ethelred the Unready' for a while. Accordingly it has been a case of, Oh look, it's the Romans... Oh look, it's the Vikings... Oh look, it's the Normans... Oh look, it's Napoleon and Oh look, it's the Germans.
Accordingly, Oh look it's the Russians should come as a surprise to no-one though I suspect the latter would have made a better job of fixing pot-holes in the roads than they are ever likely to.
For by and large we've always been fairly ungovernable by anyone except ourselves and barely that... which has ever been our best defence, and likely to remain so.
