By now most will have heard or read about the bombings on the London Underground and the bus explosion. The full details about the exact nature of the bombs have yet to be understood or revealed.
One thing seems to be apparent, and that is the anti-war lobby in this country will have suffered a blow as a result of these series of attacks. Even if the attacks were isolated or merely the start of a larger front of terrorism in this country, the general feeling will surely be to punish the people who carried out the attack. If history has taught us anything it is that a threatened nation, even when threatened by an almost invisible enemy will not worry about tact and diplomacy in trying to get revenge. The events in New York led to two middle-eastern countries being invaded. Londoners are used to terrorism, and to think that their resolve will be crushed by the bombings is a flawed hypothesis, I sense that it will actually bring people together there.
Unfortunately peace and environmental campaigners, whether they demonstrate by peaceful or other means will never gain the attention that terrorism and war generate. After all, force is the ultimate way of getting the point across, rightly or wrongly...

I would vote for exit control at ports. ie scan check passports on leaving uk so IND knows people have left country.
This is the one big hole which is not plugged at present and means people can leave the UK to be brainwashed and come back and people cannot be alerted to this fact.
Anyone who is legit cannot argue this is sensible and anyone who is planning something will have second thoughts to their plans.
Anyone which is going abroad frequently it will obvious if it is legit business or not.
A police state maybe but a safer state is better than being dead.
And how does Colin Johnston propose to implement this plan? There are
thousands of people travelling from Britain to Pakistan every year to visit their families, on business trips, etc... Are they all to be denied entry back to the UK? Or should they be followed by the secret services, in which case, is Colin Johnston prepared to see his taxes go up 8000% to pay for the costs incurred?
