Much as I dislike the EU to the extent that I have voted out already by postal proxy, there is some reasoning behind buying European. The US has bankrolled NATO for decades and is getting pissed off with the European NATO nations (apart from the UK, and a few others) not meeting their defence commitments within NATO.
Should the US decide that it doesn't want to carry on funding NATO to the extent that it currently does (or at all), then interoperability at a European level (although still within NATO) is a good idea perhaps.
Afaik, the carriers were the skimmer admirals selling the RN silver for big toys, (and for work for G Brown's constituency) when the money should have gone to more SSNs (but then, there are only submarines and targets!)
Our armed forces are run on a shoe string with the 'we can't afford to do more than this' motto attached to everything. The motto is suck it up, get on with it, and HM Forces are past masters at doing more with less, as they have been doing for decades.
The idea behind the areas of expertise is to get bangs for your buck at a NATO level. Belgium for example, has excellent MCMV capabilities, and that is more use to NATO than it having frigates that it can't man or maintain. Belgium is part of the BeNeLux grouping and they pool and share resources. There is no point small navies stretching to do everything badly, when they could do a couple of things well and cooperate with others in a defence capacity. I think we do the same with the French on some things.
I note that no other European navies apart from us and the French have SSBNs...should they all start to do so?
As for 'we have no Navy left* Really? Who then employs my db, my dn, used to employ dh, and indeed employs many of my husband's colleagues? Who crews the submarines and ships?
Yes, there is a rumour again floating round the bazaars here in Brussels about the EU having its own Armed Forces, but just think...it would cost a lot of money to stand up Forces from the ground. NATO already does all this very effectively, and is bankrolled by Uncle Sam, meaning the European NATO nations aren't having to foot what is undoubtedly a very heavy bill. Would the taxpayers in the EU member states be prepared to fork out for this? Why duplicate what is already a very successful organisation that is proven to work? I really can't see many of the NATO nations that are also EU member states just calmly handing over control of their forces to the EU, especially Greece and the UK. I can't see France doing it either for that matter. I think an awful lot of people in HM Forces would resign as well...they work for her Maj, not Juncker.
