Lets do the actual comparison , shall we? Which metric would you like, amount of information stored, people spied on, which are not accused of any wrongdoing, speed of retrieval, operational efficiency? In every comparison US intel wins hands down.

The comparison is a little unfair to the stasi, they did not have modern computers. .

But only US could place a microphone in every household and make people pay for it. Stasi wouldn't think of this.

If you are convinced it's incomparable, present some metric we can measure where US sysyem looses.
