As Obama embarks on his second term in office, he faces major challenges at home and abroad.
With a fiscal cliff narrowly avoided and the Republicans and Democrats at loggerheads in Congress, at home Obama faces major challenges on the economy.
Abroad he must forge relations with Arab countries that have elected new political leaders, whilst maintaining allies in the Gulf. Following the recent outbreak of violence between Israel and Gaza, he will be re-engaging with the peace process.
He also faces an ultimatum with Iran over their nuclear programme, the deteriorating situation in Syria and frustration over his many unfulfilled promises such as the closing of Guantanamo.
