Netanyahu congratulates Obama on re-election

Israeli Prime Minister Benjamin Netanyahu congratulated US President Barack Obama on Wednesday for winning a second term and said the strategic alliance between their two countries was "stronger than ever".

"I will continue to work with President Obama to ensure the interests that are vital for the security of Israel's citizens," Netanyahu, who has had a testy relationship with the US leader, said in a short written statement.

One major rift between the two leaders has been their approach in dealing with Iran's nuclear aspirations, with the United States urging Netanyahu not to launch any go-it-alone military action.

Netanyahu faces his own electoral test in January, when Israel holds a national ballot that opinion polls predict his right-wing Likud party will win. Netanyahu's defence minister, Ehud Barak, who was a frequent visitor to Washington over the past four years, said in his own statement he had no doubt Obama will continue his policies, which "fundamentally support Israel's security". "It is possible to overcome any differences in positions that may arise," Barak said.
