Continental Europeans sharing the same land mass have always had to be wary of the next invader. The British are not part of continental Europe: the British are like the United States in that they enjoy the protection afforded by seas. However, unlike the United States with the vastness of the Atlantic and Pacific isolating us, the British Isles are only a short sail from invaders. And, they have their history to look at: they’ve been invaded before. By forces from the north, arriving by sea.
American weakness under Barack Obama, Hillary Clinton, John Kerry and the rest of the Democrat Party politicians has set Cold War II in motion. We Americans let our oceans lull us into a false sense of security. The British do not have that seeming luxury — particular when the special relationship has become not so special, anymore.
