Isn't "routing the Iraqi Army" kind of like routing the French? There are enough sovereign nations in t6he area threatened by this group that they should be able to fight off ISIS themselves. it's not our job to police the world.
First lets ignore that we went into iraq to stop terrorists and then obama left the country without the ability to protect themselves. Then lets ignore that our allies are under attack. Then lets ignore that isis now has the man power and the money to attack Americans inside the US. then lets forget that whoever becomes controlled by isis becomes our enemy. Then lets forget that obama aided the muslim brotherhood in Egypt which failed miserably. then lets forget that iraq asked for US aid a year ago to stop isis while in the early formation stages. Then lets forget that obama helped invade Libya and then left that country a hotbed mess for terrorists to take over. And lets forget that if we had aided the Syrian rebels in their civil war before terrorists did we wouldn't be in any of this mess right now. Obviously you have no problem sitting back and watching the slaughter of innocent humans much like many Americans did before Japan invited us into world war II. In other words you don't understand foreign policy, the need for the US to have allies and why we need to stop terrorists before they come here.
We didn't go into Iraq to fight terrorists. If you think that's the case, we're wasting our time here, because you don't even understand the issue. Second, Obama didn't leave Iraq without the ability to defend itself. The Bush Administration negotiated a demobilization time table, and we spent the better part of 10 years arming and teaching the Iraqis to defend themselves. When the time came, and we had to pull out, Obama even offered to extend our stay, but the Iraqi government refused to renew the agreements that allowed our people to operate there without fear of reprisal from the Iraqi government if they decided they didn't like any of our soldiers. At least TRY to get your facts straight. If we want to concern ourselves with the potential for ISIS to attack inside the US, then we need to address that possibility and use intelligence to prevent it. That does NOT mean spending our resources over there starting yet another war with no end game on multiple fronts over there in the middle east. And lastly, stop pretending you give a shit about those "innocent humans" being killed by ISIS. You don't care about them any more than you care about the hundreds of thousands of minimum wage workers at Burger King stores all over America. You trot them out as pawns to try and vilify others who don't share your politics. That's ALL you use them for and the entire extent of your care for them. You're not fooling anyone. This is about one thing and only one thing - you hate Obama and glom onto anything that opposes him, no matter what it is, and most of the time, you don't even understand the issues. You are one of those people who never shuts up long enough to actually LEARN anything. Why does ISIS exist? Is it because Obama left Iraq? No, it's not. It's because George W Bush invaded Iraq and CREATED the power vacuum they seek to fill. We have no business trying to police the entire world. And the mess things are in exists in large part because we have TRIED to do that. And in the mean time, we are bankrupting our own country in doing so.
