Honestly, if I were the Tories right now, love of my country aside, I'd be inclined to just tell the DUP they'd pushed too far, hang it all and let the country have another election. The Tories would probably lose and then no longer have to pilot this country through terrible mess it is in for the next two terms. The only thing stopping me from saying "You want chaos, fine - call me in eight years time when you realised how much you ****** up" would be knowing what Labour would do to this country that I could prevent.
