MANILA/TACLOBAN, Philippines (Reuters) - The U.S. military's response to the devastation wrought by one of the world's most powerful typhoons has been breathtaking.
About 50 U.S. ships and aircraft have been mobilized in the disaster zone, including 10 C-130 transport planes, 12 V-22 Ospreys and 14 Seahawk helicopters air-dropping supplies from an aircraft carrier.
The accelerating relief efforts underscore a fast-expanding U.S.-Philippine military alliance that could grow even stronger in the wake of the catastrophe as the United States pursues its "pivot" towards Asia.
As U.S. ships deliver food, water and medicine, they are also delivering goodwill that could ease the way for the United States to strengthen its often-controversial military presence in one of Southeast Asia's most strategic countries.
"It is not that the United States used assistance to promote rebalancing, but that rebalancing enabled to the U.S. to respond so decisively," said Asia security expert Carl Thayer.
The Philippines is one of Washington's closest allies in Asia and a crucial partner in President Barack Obama's strategy to rebalance U.S. military forces towards the region to counter the rising influence of China.
The United States sent the nuclear-powered USS George Washington aircraft carrier to lead relief efforts after Typhoon Haiyan killed at least 3,900 people on November 8, leaving many survivors dazed and without food and water for days.
