He took a big step, but he was misguided making deals with the Devil (Sinn Fein/IRA)!!
I feel sorry for David Trimble. He sincerely thought he was doing the right thing in taking risks for peace...however he was betrayed and swindled by Sinn Fein / IRA. He just paid the ultimate political price for doing so. He deserves a nice book deal for his memoirs, a seat in the House of Lords and a peaceful retirement...his epitaph will be, "He did his best".
