What do you base that on?
Bush and his crew had the Patriot act written before 9/11 and were simply waiting around for a circumstance to justify enacting it. Honestly I'm surprised this is even a controversial opinion at this point. This is exactly what Snowden exposed. That these programs were as if not more focused on internal spying than anything else.
There were a few attempts to blow up the WTC in the 1990's and many security officials were 'sounding the alarm' on Al-Qaeda well before 9/11.
The conspiratorial views here are unsubstantiated.
Wether or not PRISM/Patriot are effective, legal or worthwhile is a huge and legit question, but they were implemented effectively for the stated objectives.
