Dave,
I still believe that the scientists say that they cannot confirm who manufactured and delivered the agent.

Only because their remit does not permit them to.
They got round it by saying they confirmed UK scientists' conclusions.

politicians who have a vested interest in it being the Russians

They do not. There interest is in exposing the culprit of an attempted double murder using nerve gas in a UK town.

The evidence must be convincing because it has convinced every EU nation, plus Canada, Australia, the US and all the other well informed liberal democracies in the world, plus the Labour Party's leadership.

The only doubters are enemies of our Western democracies like you extremists here.

Steve,
four billion people believe in God and they're all wrong. I won't try to impress you with a long list of their names.

A short list of some believers you may have heard of,
JF Kennedy, Martin Luther King. Barack Obama, Nelson Mandela, ....
All fools?
