I find it slightly bizarre that I'm posting in this thread at all, let alone sobre, but...

Not since 1066 A.D. it can't.
Not heard of the "Glorious Revolution" of 1688? Because if that wasn't an invasion, I'm Barbara Cartland. Unless, that is, William of Orange-Nassau was somehow magically English.
On-topic, we survived by the skin of our teeth
last time, and we were much stronger and had far more allies and resources to pull on then. Even so, it was massively in our favour that Germany was fighting by that point on at least two fronts. The point is that any country can be invaded. There is nothing invulnerable about the UK, any more than there is anything invulnerable about Luxembourg.
But let's take a hypothetical invasion
right now, and consider some salient points.
Consider, for example, that our foreign policy has been effectively totally spineless since the Suez Crisis.
Consider that we accepted the Marshall Plan, and are therefore tied to doing what America wants, regardless.
Consider that most of our armed forces are thousands of miles away.
Consider that after nearly seventy years of peace, the majority of the UK is slouched in front of the TV or the computer (yes, that includes you), and is effectively about as much use for repelling an invasion as a 30cm ruler.
Consider that we are drowning in debt.
Consider that our government is in its death throes, and our politics confounded.
Consider that our "nuclear deterrent" is twenty years out of date and far surpassed by those countries which have upgraded since then. And if you honestly think we'd launch... you need to watch more
Yes, Prime Minister (link [http://www.youtube.com/watch?v=IX_d_vMKswE]), and wake up and smell the delusion and tattered, long-dead glory.
Consider that our culture and our identity are stagnant and dying (and before anyone mentions anything foolish, I'd like to say I mean the likes of Tracy Emin and Stuckism).
And you honestly think we'd survive? We don't stand a snowball's chance in hell against France, let alone a major power such as the US.
Now, let's look at a different scenario, a UK in far better condition. Like that of, say, 1940. Oh, wait...
We're a fading has-been of a nation. The joke about Milwall and Liverpool fans earlier in the thread is telling in itself.
