In his 'quiet' voice Sir John Major tells a chilling message, one which we ignore at our peril.
We tend to think of 'terrorists' these days as being the Islamic Extremists.
History is young however. For the uninformed I suggest Googling The Hyde Park and Regent's Park bombings which occurred on 20 July 1982.
Dead bodies and dead horses lay motionless in the golden streets of London. The blood was on the hands of the IRA.
No-one thought there would be an end to the violence or the disruption or the terror and inconvenience of that period.
Yet, following years and years of bitterness, hurt and contempt we now have an albeit fragile peace process.
In some sectors The Good Friday Agreement is being hailed as a talisman for a peace process to be discussed with IS.
Yet this fragile peace is in jeopardy as our megalomaniac PM, the one with NO majority in the House is prepared to put peace into pieces in order to ensure an exit from the EU on a majority referendum vote from the people of 4%.
In order to gain a majority for her unwise Brexit plans Mrs May is prepared to enter a coalition with the DUP thus contravening the Good Friday Agreement.
