World Terror

The terrorist attack in Manchester should take no one by surprise, it will happen again and again.
There is little the English or the French can do to completely stop this horror barring extreme steps that are likely illegal.
It is possible that after Isis is defeated in Iraq that the motivation to perform these atrocities will go down but they may go up as well.
What might be done nonetheless?
Some Possibilities...
Immediate cessation of refugees coming to United Kingdom.
Emergency temporary arrest of all known highly suspect operatives.
British forces going to Isis strongholds and destroying Isis where it might be.
None of this will stop the next terrorist attack.
In fact this may continue for the next few years as sleeper cells may be preparing an attack right now.
In fact this is what British security services think is happening.
So all will wait for next bomb.
Carzy? Yes completely.
