Terrorism is a worldwide menace. The recent attacks in Paris, Beirut and Nigeria are proof of that. Whether it is the Islamic State (IS) or Boko Haram, Muslim extremists armed with guns and bombs are deadly dangerous. They have given Islam a bad name.
Western governments have responded to the Paris attacks by "waging war against the IS". This may be right thing to do, but it's only a short-term solution.
It has put the thousands of Syrian refugees who have arrived in Europe in a more difficult situation.
Syrian refugees in the European Union face enough prejudice and hardship, and if countries such as Germany refuse to take them, it will be a big victory for the IS.
My argument is simple. Fight back against the killers and welcome the victims.
Syrian refugees are victims of the mass destruction caused by the IS. Parisians got a taste of what it feels like to live in constant terror, and it's time we united and sent the message that religious discrimination has no place in the modern world.
We should fight the IS while helping Iraq and Syria revive their shattered economies. Because if we don't, the IS will have won.
