Yes, it would. (Assuming we're only talking conventional forces--if not France's nukes and the UK's would cancel each other out, since they have roughly the same number IIRC)
Since the 70s Germany has had a bigger military than France or UK, because due to more money, ppl, and it was nearer to the enemy. The unification did not make the military smaller, did it? France and Germany have far more ppl under weapons than the Uk, and chances are high that Spain, Belgium, the Netherlands and Italy would join a United European army. Numbers: germany: 332 800 France: 294 430 Germany + France: 627 230 UK: 210 450 Us has 1 427 000 So, Germany + France + belgium + Italy + NL + Spain would be: 1 149 460 I think that Austria, Ireland, some scandinavian nations, and some eastern european nations would be very likely to join, so just think of how much that would be... And the UK could join it too, depending on how the UKI party and the Torries do... But, the Britain and American armies are far more moodern and better equiped for a fight against terrorism... against superpower the masses of tanks Germany, sweden and France have will help though... all numbers from. http://www.bmlv.gv.at/truppendienst/milint/td_milint-overview.php?id_r=1
