Speaking specifically to the three temporary government policies you cite, if those were American policies in peacetime, then I'd agree with you that they are not shining examples of ways to treat your citizens and your country's guests. HOWEVER, it is not bright to suggest that civil liberties should be strictly maintained when a nation's way of life is on the line. Thinking long term and assuming that there is an interest in maintaining our country's strength, it makes sense to give up liberties in the short term if it means an increased ability to maintain them over a longer term.
So if the results of these tribunals and increased DOJ power is that our country emerges stronger than it otherwise would have, and therefore better able to defend and possibly spread liberty in the future, then the right decisions have been made. Assuming, of course, that the "stolen" liberties return in peacetime.
They already flat stated out loud that it was a perpetual war from here on out. perpetual means forever. This is a clue.
There is no 'return". Part of the scamwar is two class society fascism, masters and serfs, so guess which side or 'class" the cfr bush admin is on? THEY will decide for you, your input is not needed other than to bow head and shuffle on to your drudgery tasks, and don't you dare to say "no", either, anyone who says "no" is a "terrorist" by executive dictate now.
