"Pakistan has a much worse record, so by your logic they should be happy!"
I think you'll find that even countries with poor human rights records regarding the use of torture draw a line at inviting foreigners who pursue the same practices to freely enter their territory unchecked, thereby opening up the possibility of those practices being used on their own citizens.
The use of torture by the US seems to have been an accepted fact for some time now - as evidenced by feature films such as the rather good 2007 film 'Rendition' which seem quite at ease with the subject.
You aren't suggesting that because Pakistan has an iffy reputation regarding human rights, it's ok for the US to behave likewise, are you? That may be your logic, it's certainly not mine.
"Hyperbole?"
Nope - no need for exaggeration - the US has been using chemical weapons on civilians at least as far back as the Viet Nam war - we were able to watch nightly as the B52s pouring burning petrol in the form of napalm on rural peasants night after night back in the 60s.
The defoliant, Agent Orange, used as an attempt to starve the Vietnames into submission, proved to be a bit of a problem as it sent US aircraft crews home with cancer.
Back then, the US General, Westmorland, publicly proposed extending the bombing campaigns in order to "blast Viet Nam back into the stoneage".   
More recently white phosphorus has become a favourite; and in case you are still clinging to the myth that it is merely for producing pretty lights, this, from a Sunday Times tribute to photojournalist Chris Hetherington who was killed recently in Libya - the text accompanies a rather spectacular photograph of the chemical showering down on a village in Afghanistan.

"CHEMICAL REACTION
American forces detonate a device containing white phosphorus in a bid to repel insurgents around the village of Donga in the Korengal Valley, eastern Afghanistan.
White phosphorus (or WP) catches fire when its casing expolodes and it comes into contact with oxygen. It can be detonated in mortar bombs, artillery shells and short-range missiles. Its use as a flammable bomb targeted at people is highly controversial, but it can also be used to produce smoke for concealing troop movements or for identifying targets" - end of quote.

Nice to have you discussing US human rights abuses at long last, even if it is only in an attempt to explain them away - no surprise there!
