US President Barack Obama began a six-day, four-nation tour (Ireland, England, France, and Poland) May 22, 2011. His 24-hour visit to Ireland included dropping by rural Moneygall, where his great-great-great-grandfather Fulmouth Kearney lived before immigrating to the United States in 1850. The second stop on Mr. Obama’s itinerary? London, for a visit with the Queen, where he was honored with a State Dinner at Buckingham Palace and gave an address to both houses of Parliament. Mr. Obama’s next stop: a meeting of the Group of 8 world powers in Deauville, France. The leaders discussed how the West could help Egypt, Tunisia and other Arab states in political transition. On the last stop: Mr. Obama visited Poland. Last year he was forced to cancel (to attend the funeral of Poland's president) when the ash cloud from an Icelandic volcano restricted air space and travel. Ironically, a new volcanic eruption forced alterations of his itinerary again this year.
