I worked in Washington DC and it was very evident when I met a number of US 3* and 2* and discussed the issue with my 1* that the USA has a completely different mindset and approach to fighting wars than we do. Their appraoch to ROE seemed very different as well. ie our show of force low level pass bolleaux to scare the Taleban/AQ/insurgents away! Just zap the Fxxkers.
