Imagine it is the morning of January 21st, 2017: President Hillary Clinton enters the Oval Office for her first daily briefing from the CIA. Without having to do much guessing we know that this briefing will be replete with terrible news about all the many fires burning around the world. The first priority, of course, will be the Islamic State (ISIS).



Unlike her predecessor, who appeared to have mixed feelings about the use of military force throughout his presidency, Clinton appears to have no such misgivings. Hillary Clinton was a dogged champion for military intervention as Secretary of State. As a candidate, she has been among the most hawkish Democrats in living memory, outdoing most of this year’s Republicans. She has repeatedly called for “an intensification and acceleration” of President Obama’s ISIS strategy.
As president, Clinton will face few obstacles in her desire to exert decisive leadership on the global stage. In the worst-case scenario, President Clinton, in pursuit of a muscular approach to confronting ISIS, will make three related decisions that doom American foreign policy to another decade of turmoil, casualties, and terrorism.
The first decision will be to send thousands of American ground troops to eradicate the Islamic State in Iraq and Syria. U.S. military leaders have made clear publicly that they believe that as many as 50,000 troops will be necessary to dig ISIS out of its strongholds in Syria and Iraq. A determined President Clinton who sends enough troops, planes, and tanks can certainly win the military campaign against ISIS. Even so, ISIS has had years to dig in. Given this and the dangers of urban warfare, the cost in American casualties will likely be significant. Further, ISIS could disperse its fighters among the general population, returning to either guerrilla or terrorist strategy. The United States was not able to prevent terrorist attacks in Iraq or the rise of ISIS after the invasion of Iraq in 2003. There is little reason to imagine it could do so under President Clinton in 2017 when conditions in Iraq are even worse.
