That's the problem, he did not say either of those things really, but that is the simple way it is presented. He stated an obvious fact about bombing syria, more bombs kill more civilians and turn more people into extremists who then attack us. At some point, someone has to say stop, because it is not and will not ever work. We have to look for other solutions. He did though, say we would be better off if the isis guy was gone, if it could be done with no harm to innocents.
He wants to decommission trident, but he knows the party do not want that. Now more than ever is that not a good idea to work towards? We have a psychopath in North Korea and a moron in Washington both with these things and everyone is worrying, and yet still the idea we should work towards getting rid of them all is seen as odd. Beggars belief really, if anything at all in the last 70 years should focus people on why nuclear weapons are bad, it is trump with his finger on the button.
