It has been nearly a century since the last President visited Cuba. Calvin Coolidge visited Havana Cuba in 1928. Barack Obama became the first American president to visit Cuba in nearly a century, and the first since a revolution led by Fidel Castro toppled a US-army in 1959. President Barack Obama and Cuban President Raul Castro shook hands Monday in Havana's Palace of the Revolution, a great moment in history for two countries working to put the bitterness of their Cold War-era enmity behind them. Obama and Castro stood together as a Cuban military band played the national anthems of Cuba and the United States - stunning sounds in a country where resistance to the U.S. has been part of the national mission for decades. Greeting each other warmly, the two leaders inspected an honor guard before sitting down in front of American and Cuban flags. There has been wide support for President Obama to open talks with Cuba and reconcile their differences. Of there has been skepticism with Obama's historic trip to Cuba with uncertainty and tension for both governments President Obama was joined by first lady Michelle Obama and his two daughters, Obama toured Old Havana and the historic Havana Cathedral. For Obama, there was no better place than Havana to show that engagement can do more than isolation to bring about change on the communist island. Yet for the Cubans, the glaring question is whether their own government is ready to prove the ambitious diplomatic opening is more than just talk. American companies, eager for opportunities in Cuba, were wasting no time. Obama announced that tech giant Google had struck a deal to expand Wi-Fi and broadband Internet on the island 90 miles south of Florida. The two countries hope they can settle their differences, such democracy, human rights, and economics. Obama has taken sweeping steps to lift decades-old U.S. restrictions on travel and commerce, and American businesses have eagerly followed suit. If the trade embargo is lifted Americans will be able to travel and trade freely. Paying tribute to another Cuban independence hero, Obama adjusted a wreath at the foot of a 59-foot statue of Jose Marti, calling his trip "a historic moment." "It is a great honor to pay tribute to Jose Marti, who gave his life for independence of his homeland," Obama wrote in the guestbook. "His passion for liberty, freedom, and self-determination lives on in the Cuban people today." The long-awaited meeting between Obama and Castro was one of the most scrutinized moments of Obama's 2\u00bd-day trip to Cuba, the first presidential visit in nearly 90 years. The White House's attempts to get Castro to agree to a joint news conference appeared unsuccessful, and it was unclear whether they'd answer questions. Joining Obama and Castro was Cuba's First Vice President Miguel Diaz-Canel, considered Raul Castro's possible successor when the president steps down as promised in 2018. On his first full day in Cuba, Obama also planned an event with U.S. and Cuban entrepreneurs aimed at championing Cuba's fledgling private sector. He was to be feted in the evening at a state dinner, an honor illustrating just how far the U.S. and Cuba have come despite their deep ideological differences. As Obama's visit opened, Western Union announced expanded processing for remittances, and hotel chains Starwood and Marriott said they'd received U.S. permission to operate here. Google planned to open a cutting-edge center at a Havana art studio offering free Internet at speeds nearly 70 times faster than what Cuban citizens can currently access. Since succeeding his brother Fidel in 2008, Castro has orchestrated economic and social reforms with broad-based impact, though they appear slow to materialize. Not only are hundreds of thousands of Cubans now able to pursue free enterprise, but restrictions on cellphones and Internet have been eased and citizens feel more comfortable discussing Cuba's problems. Yet Castro hasn't budged on changing Cuba's single-party system or easing strict limits on media, assembly and political dissent. Repeatedly, his government has chided Obama for saying he wanted to empower Cubans.
