ISIS is making enemies in many countries and it continues to make new targets. At some point it will become impossible to deny that ISIS needs to be stopped and everyone uniting against them is the only real way to do that. As a terrorist organization ISIS is attacking countries across the globe as they continue to try to gain ground in the Middle East. It is going to take a united effort to defeat not just the core of ISIS in the Middle East but to root out the terrorist cells that exist throughout the world.
When it comes to wanting the security of their governments and safety of their citizens, all countries are the same. Each country will momentarily put aside differences to defeat the common enemy of ISIS. No country will let terrorist acts disrupt their country without justice and the only way to get justice against ISIS is to work with countries with that same goal.
Most of the world, muslims and non-muslims alike are against ISIS. How the world will deal with ISIS has yet to be seen, but it is clear that they do not have many fans, and that there are few people who do not seem them as a threat and are not concerned.
I think many countries will get together to fight Isis because so many strong countries have ben affected by attacks. I think it would also be smart to combine forces instead of having several individual countries all take different angles. Teamwork will work better and it even might overwhelm Isis.
