Interesting article, but in fact the US mostly does exactly what it wants to, and gets away with it.
There were a minority of voices saying similar things in the run-up to the Afghanistan and Iraq 'wars'.
Everyone (D's and R's) lined up behind GW Bush when he went into Afghanistan, and then Iraq, and the cooler heads did not prevail.
At least this time, people in Congress are attempting to do their job, by questioning the President on his rationale and/or legal standing - I would have liked to have seen some more of that in the run-up to the two 'wars' perpetuated by CheneyOilCo.
Cameron got his
handed to him when he went in front of the British Parliament seeking the authority to strike without UN or Security Council authorization...it's ironic that the kingdom we rebelled against has a more functional government than we do.
Unfortunately, the US is unlikely to wait for authorization from anyone, as if 'authorization' is even realistic, given the deep divides between the major players/organizations.
But hey, true and necessary legitimacy for military action has never stopped us before, and it certainly won't stop us now.
Go Team!
