President Obama recently announced that he would keep more troops in Afghanistan in 2016 than previously planned—a good decision for regional stability and America’s national security interests. Unfortunately, the President continued his pledge to reduce those numbers on an arbitrary timeline rather than basing that decision on ground conditions.

But this came on the heels of the President’s planned decision to hobble our military by vetoing the bipartisan National Defense Authorization Act (NDAA). So why would the President decide to keep our troops in harm’s way while also blocking authorization to fund defense? These two actions together make absolutely no sense, and will put our troops at risk—the height of irresponsibility.

Making his likely decisions even more inexplicable, the President doesn’t actually have any problem with the NDAA itself. In fact, the bill matches the exact level of funding the President requested for defense discretionary spending.

The real problem is that President Obama is using the well-being of our military as a bargaining chip while putting our servicemen and women in harm’s way, all in an attempt to make Congress increase domestic spending at a time when we face a dire debt crisis.

There are so many problems with what President Obama is doing its hard to begin, so we’ll make it easy for him. President Obama should stand with our military, support national defense, refuse to exacerbate our debt, and work with large bipartisan majorities in Congress by signing this bill. Because vetoing NDAA is not only irresponsible; it just doesn’t make sense.
