You're displaying some flawed logic here.
Regarding Iraq:
"Can I slightly reword that to say I think any prime minister taking a country into war has got to be straight with the nation and carry it, so far as possible, with him or her. I don’t believe that was the case in the Iraq instance.”
Blair misled the people.
Regarding the GFA, firstly the GFA wasn't at all possible without the Security Forces having brought both PSF/PIRA and the UDA to their knees. It's why both sets of terrorists worked together to try to destroy Special Branch. The Security Forces saved 16,000 lives during the Troubles.
It was this that led to the GFA as the GFA was not hugely different from Sunningdale 1974. It was dubbed "Sunningdale for slow learners".
Your flawed logic shows itself as a False Dilemma Fallacy as the choices were not between conflict continuing or not continuing without Blair's secret PIRA On The Run deals.
Since the Security Forces had the upper hand which several PIRA terrorists have since admitted, they would have agreed to the GFA anyway.
Between the success of the Security Forces and the strength of the SDLP, PSF/PIRA knew they was nowhere else to go but the GFA in order to save their own necks.
Blair perverted the work Major had done between 1990 and 1996. The secret OTRs were NOT part of the peace process at any stage.
Of course, Blair lied to the people about the GFA and he knew it had the potential to bring down the GFA itself. It's precisely why his government kept that secret until 2014.
Paisley? Ugh, what a nasty man he was as well! He's in good company with McGuinness for shit stirring and being responsible for murders too. These people were only saving their own necks.
McGuinness was never an "ex leader" as his gravestone reveals to this very day. Indeed, while Deputy First Minister of Northern Ireland he defended PIRA atrocities including the human bomb murder of Patsy Gillespie.
None of this changes the central point - Blair lied about the GFA promising there would be no secret deals with the Provos.
Until it came out.
The SDLP warned him. Unfortunately for everyone, Blair admitted admiring PIRA Commanders Adams and McGuinness more than he should have. So, letters reveal he knowingly authorised the secret OTRs at the expense of the Security Forces and PIRA victims.
Lied with Iraq and the GFA. No wonder he's the most despised politician of the last 30 years.
