Nancy Pelosi on Brexit: why Irish-US diplomacy is a powerful force in border talks Nancy Pelosi's message to London - don't even think about it! ...she stated that “if there were any weakening of the Good Friday accords there would be no chance whatsoever, a non-starter for a US-UK trade agreement …Has anyone feeling that timing of her visit was rather calculated before POTUS will manage to do "his magic" during his forthcoming visit? Poor Brexiteers. Fighting among themselves, fighting with PM, fighting with House Speaker, and now Nancy stepped into it. What the world is coming to after three years of dreams?
