I think it's a complex problem that needs a complex solution.

Government Intelligence should be increased so that more plots could be unearthed before disasters happen.

Known terrorist plotters and offenders in our country should be arrested and imprisoned.

Radicalised young people should be approached with an intent to listen and try to understand their mindset. Young men who feel isolated and unaccepted should be reassured and encouraged.

Politically we should keep our noses out of regimes and governments which are none of our business.

Individually we should try not to become racist or condemn whole sections of our population for the actions of a few. We should see all human beings as of value.

We should all try to hold on tightly to the spirit of tolerance, acceptance and fellow-feeling which has been a characteristic of many ordinary folk in our country. (As shown in Manchester by the mutual support and friendship of many religious groups and races)
