I believe as a US citizen I have no say in how they make these decisions so this thought exercise is pointless. We all structure our governments differently and so compete globally with differing rules, I only care about how we do it here in the US. At times, what we do may be in reaction to others, but how we do it needs to be agreed upon here at home and for that we have a Constitution that gives this power to congress not the executive. I'm glad the court got it right, it's a glimmer of hope that the constitution still has some meaning.
