New York: Democratic Presidential front- runner Barack Obama has challenged President George Bush and presumptive Republican nominee John McCain to a debate on the foreign policy, saying they have a lot to explain on issues like Iraq war, Iranian nuclear programme and Mideast conflict.

The challenge came yesterday as analysts said Bush's statement comparing those who want to talk to Iran with politicians trying to appease Hitler before the Second World War has given a major opening to Obama to inject himself in the debate on foreign policy at a time when the President's approval ratings are at the lowest.

His attempt would be to turn the debate around on the contention of Republicans as also his party rival Hillary Clinton that he is inexperienced in dealing with foreign leaders and policies.

Analysts said that Obama's inexperience is expected to be a major plank of Republicans who have little to show with economy going into recession and stalemate in Iraq.

Saudi Arabia's rejection of Bush's proposal to increase oil production is likely to be exploited by Democrats who could argue that it shows decreasing American influence in the Middle East.

In campaign speeches yesterday, Obama sought to blame the policies followed by the Bush administration for increasing trouble in the Middle East including rise of Hamas.

He held unpopular war in Iraq responsible for rise of influence of Iran in the Middle East and asserted that such policies are not going to work.

Obama likened policies advocated by McCain to the failed policies of Bush in his bid to emphasise that election of McCain would mean third term for Bush, a theme which is likely to repeatedly recur in the heated and no-holds-barred campaign expected for November's Presidential poll.
