You can only vote with your conscience and maybe you're onto something with Federalism. WWII was twenty years in the past when I was born but I grew up steeped in it: making Airfix kits of warplanes & tanks, endless war films on TV (rare, these days, given the vastly expanded back catalogue), documentaries (no nannying-blur on the gory bits). I am thus as retro in my views on the machinations of certain nations' elites as someone born in the 40s/50s. I am a walking anachronism, if you will.
Militarily, 50 unassociated states, 2,000 miles from us would have little or no clout in our affairs (manufacturers of certain tech products, aside, that is). Their federation gives them clout, on the world stage.
If this isn't what the EU is working towards, then I have no clue what it is they're really up to, other than subsidising inefficient farms and having a hoot with net contributors' money.
I would like some sense that my taxes are going to be spent on things near enough to me that I actually get to use them (less bone-jarring road surfaces would be a start).
