If that is his logic then it is flawed. The attack on Glasgow Airport, for example, was carried by home grown sympathisers. They are the most potent threat and this action will only increase the threat.
If the intelligence is correct, and we are high on the target list, and their command centres can be bombed - it doesn't seem that unreasonable to me to bomb these targets, if the intelligence is correct.
Reminds me of WMD and 45 minutes claims.
Of course there's always the argument that the effects of these bombs may breed more extremism and further increase the risk, but the line from the government is that the terrorist threat is already so high - that it's more risky to sit and do nothing, especially when our allies (who are already taking action) are asking us to join in and help..
Tokenism at its best.
I'm personally undecided myself, I listened to almost ALL of the debate in parliament yesterday, read what the analysts have said, and I just do not know what it's best to do, and nor do I claim to.
The BBC's security correspondent said there are 110 groups fighting in Syria, some against Assad some pro ISIS, some changing sides frequently. He also said Cameron's 70000 troops fighting against Assad was comprised of people with different agendas and allegiances. The biggest danger as mentioned in Parliament was so called 'mission creep' where UK ground troops will be deployed. Nobody with experience has said that air attacks will defeat ISIS. General Dannat made that point yesterday.
