U.S. willing to attack ISIS

In an article written by Helen Cooper, Matthew Rosenberg and Michael R. Gordon called "U.S. is Willing to Use Attack Helicopters to help Fight ISIS", the United States is planning on assisting the Iraqi army on fighting against ISIS. The weapon of choice are Helicopters. This in my opinion is a huge step because there are many risks, but it is something The U.S.is willing to do to stop the fighting. The Pentagon officials are also willing to take this risk because there aren't that many people and they're not giants, so an airstrike should be enough to obliterate them all at once. The authors tone seem like they agree to what the U.S. is doing, but in my opinion I feel that using helicopters is just overdoing it and could take a lot of money just to destroy 20,000 to 30,000 people. It is complete overkill.
