we never used to do this so why now??
it all smacks a bit of facebook campaigns or Dianas Funeral again
Pretty much.
The original 2-minute silence, for those lot to war and the utter halting of everything (as it used to be, anyway) designed to make people actually think about how bad it was, why it should never happen again, etc, is still fairly effective.
But in the modern world, where every special little ********* wants their limelight just because of one thing or another, it's more just a competition for attention and any genuine sentiment behind this move is consumed by that same competition mentality.
IMO, giving so much attention like this just helps sensationalise events and bolster the terrorism, exactly the opposite of what we should be doing.
Back in the 'old days', there were three options - The IRA blew up you or your family and it was terrible for you but so common no-one else cared, the IRA bomb disrupted your journey home and you tutted about it before getting out the paper to read, or you read about it afterward and tutted before getting on with your life.
Some nations scream and shout and rant and rave and weep and wring their hands (inviting everyone else to wring hands) before going on massive missions of vengeance... because they are terrified and thus terrorised. But you cannot terrorise a nation that isn't more than mildly inconvenienced!
