An “unsustainable” debt course.

That’s how U.S. Sen. Jeff Sessions, R.-Ala., described America’s path, thanks to the politics that plague Congress and the inability of our nation’s leaders to pass balanced budgets.

With a $17 trillion national debt bill, and the addition of another $7.3 trillion in debt projected from this year’s budget, debt has become the single largest item in our nation’s budget. It’s so large, Sessions said, that in 10 years we will be paying an estimated $800 billion in debt interest.

In other words, an unsustainable amount.

Of course, we all know this. But few are willing to make the difficult decisions and sacrifices necessary to reverse this course, especially among the Congressional leaders who seem more concerned with politics than purpose.

The reality remains the same: Our nation’s financial crisis continues to loom as the biggest threat to our national security and our future. And it continues to be the single most difficult issue for our political leaders to resolve, because it requires the setting aside of politics and partisanship and the willingness to make difficult and unpopular decisions.

Sen. Sessions is right. Our course is unsustainable.

But who will step up and change it?
