London - the victim of another terrorist attack.

Terrorism hits Westminster and London looks on in horror.

London once again looks on in complete horror and disgust. Once again the capital city of Britain could only bow her head in shame and disgrace as terrorism cuts the ugliest slash through the heart of a peaceful, law abiding city. It is the most grotesque attack on our civil liberties, a violation of our freedoms and a reminder - if it were needed- that London is still fragile, vulnerable, exposed and silently threatened by the forces of evil.

Westminster, the heart of the political establishment, could only express its shock and astonishment as, at the time of writing, four people are now confirmed dead and an increasing number of injuries have now been identified. It all seems horribly familiar and humanity has to wrestle with its conscience. The knee jerk reaction is to simply utter our revulsion and point the finger of condemnation but the truth is that the whole world has to be at its most prepared and equipped for both the ferocity and violence of terrorist outrages and their grisly aftermath.

After the terrorist attacks that have disfigured both Paris, Brussels, last year and Tunisia, the world has to be ready for the worst of all scenarios. Sadly, inhumanely and all too frequently now, Paris has suffered terribly from the appalling assaults on both its people and city. Terrorism is now stalking the streets, cafes and restaurants of a world that can hardly come to terms with the sheer cold blooded savagery of murderous minds. But London must reveal a stubborn defiance and backbone that will never buckle in the face of adversity.

And now London finds itself at the centre of events, a seething metropolis that simply wants to get on with the business of going about its every day life with civility and rational thinking. None of us could possibly have legislated for the sheer brutality of today's dreadful act of bloodthirsty terrorism. But it happened once again and now is surely the time to show the rest of world that London must never ever give in to the forces of despicable manslaughter.

But at another critical point for world peace it is time for both London and the world to show that we will never succumb to violence, death and deplorable aggression. It is now time to stand firm against those whose sole objective is to kill, maim and injure. It is a time to demonstrate British strength of character, sheer indomitability of spirit and a raw determination to carry on and never be deterred when faced by hatred and prejudice.

In the aftermath of 7/7 we all believed that London had been hit hard and abominably by terrorists. The trains and bus that cruelly claimed so many lives on that fateful day will leave the most repulsive legacy for years to come. The defence of London, the security measures and reinforcements that have always been put into place, are a cautionary metaphor for just how ready London has to be in the event of tragedy and disaster.

We must have thought that we'd seen the worst of all terrorist catastrophes when New York was horrifically traumatised and emotionally destroyed by the destruction of the Twin Towers on an early September morning in 2001. We have to believe that the forces of  good will triumph over the cruel face of racism and intolerance. It is time for the reasonable voices of peace and harmony to express themselves, turning their back firmly on the dark face of racism and anger.

 We have to rise up against those who would deny the right to live our lives and live in a civilised democracy. We have to believe that London, Paris, Brussels and all points of the global compass will be victorious and will win the war against terrorism. It may sound simplistic and logical but without the calm voice of reason the world will continue to shudder and tremble when the bomb, bullet and grenade are the only options.

The world has to combine forces and make the loudest and boldest of statements on world peace for ever more. We have to believe that humanity will never tolerate the latest atrocities that have broken into our wonderful world. We have to live as a united and harmonious world population and never let the murderers win their disgusting and nefarious battles.
