The UK has somewhere in the neighbourhood of 160 functioning tactical nuclear weapons.
You would need to launch 161 separate invasions, assuming it isn't the 'States or Russia doing the invading. If it is one of them and the situation goes nuclear there won't *be* a UK to invade, just a deep ocean trench and Southern Ireland.
