Yes, the world needs to do more to fight terrorism. It is every country on earth's duty to try to combat terrorism. If all countries cooperate, this will let terrorists know that there is no place for them. People can no live in fear of terrorist attacks all of the time.
Yes, the World needs to do more to fight terrorism. It is a constant battle and it requires vigilance on all fronts as well as incredible communication and cooperation. Unfortunately, not all countries screen at the same level and they certainly don't seem to be communicating effectively. The battle against terrorism will unfortunately be a constant battle.
Many across the World are showing their support for the victims in the Orlando terrorists attack. There is, however, much more that the could be done to fight terrorism. The civilized World should unite to defeat ISIS. Moderates in the Middle East need to condemn these radicals and dissuade others from joining ISIS. Countries need to commit the resources it will take to defeat this group as well.
The world, as a whole, needs to be more proactive to terrorisms as opposed to reactionary. We are far to caught up in dealing with a tragedy after it occurs than in dealing with the problem as a whole before tragedies are able to occur. While terrorism is not something that every be completely erased, it is something that be controlled and better regulated.
