Being pragmatic we in Europe do need to stick together the logistics of remaining on our own seem to be incalculable,already the uks aircraft carriers are due to have er---no aircraft it is rumoured French planes wil be flying from them,the french ie EDF are due to build the next generation of nuclear power stations in the uk,and the germans own some of the power suppliers we currently have,need i mention BMW owns the mini plant and even Rols Royce ,and the french licence vans that are built in Luton.
Now i am European and am proud of being so,i suspect if the poll was do you want to be a part of the united states of america the answer would be different or am i being too cynical,would not want to be in the "51st" state myself,but am quite willing to be a part of the region in which i live.
The above are just examples of the European investment the uk gets in.
