When France, England, Spain, Germany, Portugal, Turkey, Denmark, etc. etc. are ready to send their soldiers, as they all face a much higher imminent risk than does our country, then come back and ask again. We went alone in Iraq and totally destroyed that country. We have been essentially on our own in Afghanistan, same outcome. Ground troops will swat at sand dunes. You can't kill ideas with bullets and it is exactly what ISIS wants, proof they are right that the US is out to destroy their vision of Islam
