In case you haven't realised it, as an island, we are actually situated in a very strategic position. Whoever rules the UK could have reign/control over the English Channel, North Sea, Irish Sea and the seas around Scotland. It would shorten the distance to also have a major influence in the North Atlantic Ocean which could make things more accessible to carry out nefarious activities against others and help to isolate European countries from overseas allies.
Think back to your history of WW1 and WWII when Germany captured Belgium, France and the Lowlands. Their military were able to strike further sooner.
So do you really think others are not interested in this country?
