engineer,
Americans rarely care who is visiting the White House, it doesn't matter if it's Merkel, Sarkozy, Hu Jintao or Cristina Fernandez De Kirchiner. Very few Americans care about international politics, heck they don't even care about their own, so it's understandable.
However, other nations are different - state visits are highly publicized and
they're very much aware and interested in the politic of other countries, especially EU countries.
