Around 8 o’clock in the morning, daily at Obama’s Chicago campaign headquarters, his foreign policy aides sends him two emails. One mail briefing him on major developments on world developments over the previous 24 hours and other email is a set of questions likely to be asked about international relations and suggested answers. All these arrangements are in the wake of concern of many voters who thinks Obama lacks foreign policy credentials and national security experience. “ It is unwieldy , no question”, said Denis McDonough, Obama’s top foreign policy aide, He says, 20 teams are divided based on regions and issues.

This group is on the spot as Obama planning to make his first overseas foray as the presumptive Democratic presidential nominee. All the voters at home and leaders abroad will closely watch at him on how he handles the things on the global stage.

Unlike George W. Bush, who entered the presidential race in 2000 with scant exposure to national security issues Obama has served on the Foreign Relations Committee since his election to the senate in 2004,. Obama has a running tutorial from aides steeped in the issues. His core members of his team had served in government during President Bill Clinton’s administration. His campaign says that he is well prepared and often alters and elaborates on the talking points provided to him by his foreign policy advisers.

Obama’s infrastructure, channels hundreds of email messages and detail papers and discussion points each day to members of the core group. This core group seeks advice and makes requests for more information to the team members down the line. Key officials frequently asks help on framing Obama’s comments on Iran’s nuclear program and its potential threat to Israel, says Ross, who participated in a conference call last week with Obama and other advisors to prepare for Obama’s foreign trip. Ross, who is accompanying Obama’s foreign trip says, during conference call Obama focused on “drilling down” into the issues on the trip.

Obama's Republican rival , Senator John McCain has 75 people as foreign policy advisors in operation and they are not organized into teams.

One point to be noted that is, in 2004 the democratic presidential nominee, Senator John Kerry who had spent 20 years in the Senate, had a foreign policy structure similar in scale to Obama’s. But that setup has a limited influence on the candidate when comparing with Obama’s case.

But certainly Obama’s overseas trip will be a high risk debut on the world stage . It has potential pitfalls at least as numerous as the likely rewards.

“It is a high stakes trip , but its one Obama needs to take," said Cal Jillson, political analyst at Southern Methodist University in Dallas, Texas.

Obama’s rival McCain is a four term Arizona senator and also a former Vietnam prisoner of war and served as U.S representative. He has tinted his military and foreign policy credentials. Obama’s mistakes during foreign trip will underscore the criticism and reinforce Republican rival John McCain’s point that the first term senator from Illinois is a risky choice for the White House.

McCain is thought to have a good knowledge of the world by a margin of more than 2 to 1 than Obama, on his ability to deal with an unexpected major crisis.

"It's an opportunity for him to sit down with the international leaders with whom he would have to work as president of the United States, and discuss some of the issues," said David Axelrod, the campaign's senior strategist.” There will be a lot of eyes on him, and we know that," he added when asked about the risk of politically damaging errors.
