As protests and uprisings rock the Middle East, many affecting vital US allies, the White House fails to calibrate a uniform response to the crisis.

Barack Obama, the US president, wavered between strong support for protesters in Iran as the government there heavily cracked down on them, to ambiguous statement on Bahrain, where a major US military is based.

The US says it  will not dictate events in the region.

Many find the US response disappointing, and some feel the White House will only react strongly to those governments it does not have a stake in.
