Guantanimo

How is it the Supreme Court is able to tell the Bush administration how
to conduct war? Doesn't that violate the separation of powers in the
Constitution? If the SC is able to declare such things as the prisoners
of war housed in Guantanimo should have the same rights as Americans and
that Guantanimo is part of the United States, why couldn't they start
declaring such things in Iraq? What about the way the spies are
conducting things across the globe?

It is interesting the Supreme Court isn't making big declarations about
the behavior of the folks in the UN!
