Peg, et al,
Over-reacting? Maybe - but what precedent is there for our reactions?
On this side of the Atlantic we have had our share of rubble, violent death and destruction, with the inevitable stark images of shattered buildings and broken lives; Guildford, Birmingham, Warrington, Bishopsgate, Enniskillen, Omagh and dozens more.
All of them have made an impact on our national consciousness, and all of them have led to cries for vengeance and retribution that inflamed rather than salved an age-old wound.
Those attrocities - and attrocities they were - cannot singly or together compare in enormity to what happened on Tuesday.
So there really is no yardstick for reaction - which for me is very worrying, as the rhetoric and bullshit flies and both the fond and the foolish reach for a flag in which to wrap themselves.
Time, maybe, to remember the wise words of someone else to whom both our countries have reason to give thanks - Tom Paine.
"My country is the world, and my religion is to do good."
So don't apologise m'dear. Not to me, at least!
