Is Britain a superpower?

This made me chuckle - not to be condescending but this utterly idealist. Co-operation via a US-lead doctrine

I never "missed" out any potential superpowers, because I wasn't listing potential superpowers in general. The potential superpowers that I even listed were in context - i.e. those where Britain had a considerable influence, previously colonised.

You cannot pass over the fact that globalism is becoming all-pervading, no? Globalism is the new order of the day - this is why nationalism is looking pettier and pettier everyday and is losing importance.

If a state wants to follow the money and be successful, they must look to globalism.

It's not though, look at how international politics has gone since WW2, it's all about economic and political co-operation.

Political cooperation does not necessarily follow on from economic - just look at the countless despotic regimes Western states sponser via economic cooperation; this despite not towing democratic values etc.

Political and economic co-operation go hand in hand though. Look at how France acted after WW2, it tied Germany town with the ECSC, it used economic co-operation to bring political co-operation. I'm fairly drunk so I'm probably failing massively at explaining myself coherently, but I just wrote an essay on a similar subject so I will come and explain myself better tomorrow.

The UK's influence remains considerable to this day; it's not the backwater many of its more pessimistic residents like to portray.

However, it isn't a superpower by any means.

Primarily because it tows the US line - without which it would just be another sorry state. Im saddened by that to some extent - and it should be motivation for the citizens to change things. Sadly most of us are far too apathetic or willing to bask in the lukewarm sun as it finally sets on the Empire - the phrase "the sun never sets on the british empire" is truly dead and buried now.

I completely disagree. Britain would remain a great world power without supporting the US to the extent it does now; indeed, I think it's a misconception that they have our unequivocal support. Certainly, the UK is in a better position that it would be for it, but I think it's awfully dismissive to deem us a third rate state without them.

Russia is absolutely not a serious economic power

A superpower is a state with a dominant position in the international system which has the ability to influence events and its own interests and project power on a worldwide scale to protect those interests.

You can argue it many ways as part of the EU technically on its own id more say great power though.
Although according to wikis definition;

We do to a certain degree fulfill that do we not?

Thats a mere definition - now tie in our capabilities with those of other states and you will find the image is not so rosy.

Yes we have nukes - but the military is being stripped down rapidly. You cant use nukes in skirmishes or localised conflicts.

Re-read your first line and think about it again. By definition Russia is more than capable of being on a military par with the US [at least in terms of flattening the world] yet theyre barely meriting great power status these days by standards...
Besides the comment was somewhat flippant.

I beg to differ, if Iceland decided to sink a boat then we could quit happily drop a nuke on them... technically nothing is stopping us bar common sense.

Yeah but your assuming that the UK would be willing to use a nuke. Think about history and you will know that has not happened (even when the falklands were invaded). Russia has indeed the capacity to flatten the world - but that implies that diplomacy is akin to a child who wants something - tantrums dont solve crises.

My point: UK/Russia are both great powers, but the UK compared to the US or even China is pretty much nothing. The principal reason the US uses the UK in join ops is to add legitimacy to said ops
