First of all, the Mosconi Cup has always been about the US and Europe. Second of all, it is not the UK, because the UK is a country whereas Europe is a continent. As far as I know Peach is the only guy from the UK on this year's european team.
Thirdly, what makes you say the US should play an asian team to make the matchup more even? I am sure that the best european players would kick the US team's behinds. Unfortunatly, politics makes the Europeans not send the best players out there... That's why Mika is not there, or Hohmann, or Ortmann, etc...
