Terrorist organisations breed off each other. That is their strength. No individual organisation could survive without the finance, weaponry, technology and training that it acquires from another. That they all help each other is their lifeline and what makes them the force that they are. They trade in a currency of terror. Greed among business people allows them make financial investments or buy the equipment or expertise they require. Tolerance of terrorists' causes, turning a blind eye or supporting them, if only in a tacit way, by subscribing to one of their shadowy umbrellas for relief does not make for pleasant co-operation among states. States should face up to their responsibilities in facing down the regimes within their own countries.
